3 cups of tea and 4 cups of coffee costs £3.45 in total.
4 cups of tea and 1 cup of coffee costs £2.65 in total.
How much would it costs to buy one cup of each in total?
Answer:
A) 3T + 4C = 3.45
B) 4T + 1C = 2.65 We'll multiply this by -4
B) -16T -4C = -10.60 then we'll add A)
A) 3T + 4C = 3.45
-13T = -7.15
Tea is .55
and coffee is
A) 3 * .55 + 4C = 3.45
4C = 3.45 -(3 * .55)
4C = 1.80
coffee is .45

in a sequence of numbers, a3=3, a4=7, a5=11, a6=15, and a7=19. based on this information, which equation can be used to find the nth term in the sequence, an?
Answer:
Step-by-step explanation:
sequence is a1,a2,a3,a4,a5,a6,a7,...
or a1,a2,3,7,11,15,...
d=a4-a3=7-3=4
a3=a1+(3-1)d
3=a1+2d
3=a1+2×4
a1=3-8=-5
an=a1+(n-1)d
an=-5+(n-1)4
an=-5+4n-4
an=-9+4n

Someone help me I don’t know how to do this
Answer:
17 and 59
Step-by-step explanation:
90-75=17 first one
180-121=59 second one plz give me brainnessttttt pllzzzz
Hey there!
So the first angle is a complementary angle, meaning that two angles put together will equal 90 degrees. Since we already know that one angle is 75 degrees, all we need to do is 90-75 and we get 15 degrees, which is the value of the missing angle.
The second angle is a supplementary angle, which means two angles equal 180 degrees. Since we know that one angle is 121 degrees, we can take that and subtract is from 180 degrees to get 59 degrees, which is the value of the missing angle.
Remember:
A complementary angle is made of up TWO angles that add up to 90 degrees.
A supplementary angle is made up of TWO angles that add up to 180 degrees.
I hope this helped!!!
Find the value of the variable(s). If your answer is not an integer, leave it in simplest radical form.
x=10/3 x=10,y=30/3 x=30.y=10/3
Answer:
Use the fact that sin(x) = opp/hyp and tan(x) = opp/adj
where opp=opposite, hyp=hypotenuse, adj=adjacent and recall sin(30)=1/2 and tan(30) = 1/sqrt(3)
sin(30) = 1/2 = 17/y
y = 17(2) = 34
tan(30) = 1/sqrt(3) = 17/x
x = 17sqrt(3)
So the answer is (d)
Note that you could have also use the Pythagorean theorem to find x instead of using tan(30).

What is the mean of the values in the dot plot?
Enter your answer in the box.
Answer:
The mean is 46.
Step-by-step explanation:
To find the mean of these points add the values together. So that's one 40, two 41's, one 45, two 48's, three 49's and one 50.
40 + (2 * 41) + 45 + (2 * 48) + (3 * 49) + 50
Multiply what's in the parentheses.
40 + 82 + 45 + 96 + 147 + 50
Add, going from left to right
122 + 45 + 96 + 147 + 50
167 + 96 + 147 + 50
263 + 147 + 50
410 + 50
460
Now, divide that by how many dots there were (10).
460/10
The mean of the values in this dot plot is 46.

Write an equivalent expression by distributing the "-−" sign outside the parentheses: -(-4.2w-7x-5.4)
Answer: 4.2*w + 7*x + 5.4
Step-by-step explanation:
Here we need to remember how the product of different signs works, here is the rule:
(+)*(+) = (+)
(+)*(-) = (-)
(-)*(+) = (-)
(-)*(-) = (+)
Now we want to distribute the negative sign in the equation:
"-(-4.2w-7x-5.4)"
We can write this as:
-(-4.2w-7x-5.4) = (-1)*(-4.2w-7x-5.4)
Now we can distribute the "-1"
Then we get:
(-1)*(-4.2w) + (-1)*(-7x) + (-1)*(-5.4)
We have 3 cases where we need to use the "(-)*(-) = (+)" rule, then we get:
(-1)*(-4.2w) + (-1)*(-7x) + (-1)*(-5.4) = 4.2*w + 7*x + 5.4

The rectangle is 16 inches by 25 inches. If the scale is 4 in :5 ft what is the length and width of the rectangle in feet.
Answer:
The length and width of the rectangle are 20 feet and 31.25 feet, respectively.
Step-by-step explanation:
Let the scale be [tex]4\,in\,:\,5\,ft[/tex] and the dimensions of the rectangle being 4 inches and 5 inches, respectively. The scale ([tex]r[/tex]), measured in inches per feet, is equivalent to the following rational number:
[tex]r = \frac{4\,in}{5\,ft}[/tex]
We can convert each length by dividing it by scale factor. That is:
Length
[tex]l' = \frac{16\,in}{\frac{4\,in}{5\,ft} }[/tex]
[tex]l' = 20\,ft[/tex]
Width
[tex]w' = \frac{25\,in}{\frac{4\,in}{5\,ft} }[/tex]
[tex]w' = 31.25\,ft[/tex]
The length and width of the rectangle are 20 feet and 31.25 feet, respectively.

The deck that Amos is building is in the shape of a parallelogram, DGRY. The measure of
Complete Question:
The deck that Amos is building is in the shape of a parallelogram, DGRY. The measure of D is five-halves the measure of Y. Find the measure of each angle of the deck.
Answer:
[tex]\angle G = \angle Y = 51.43 ^{\circ}[/tex]
[tex]\angle D = \angle R = 128.57 ^{\circ}[/tex]
Step-by-step explanation:
Given
Shape: Parallelogram DGRY
Dimension: [tex]\angle D = \frac{5}{2}\angle Y[/tex]
Required
Find the measure of each angle
D and R are opposite sides & G and Y are also opposite sides.
So, we have:
[tex]\angle D = \angle R = \frac{5}{2}\angle Y[/tex]
and
[tex]\angle G = \angle Y[/tex]
The sum of angles is given as:
[tex]\angle D + \angle G + \angle R + \angle Y=360^{\circ}[/tex]
Substitute values for [tex]\angle D, \angle G \ \& \angle R[/tex]
[tex]\frac{5}{2}\angle Y + \frac{5}{2}\angle Y + \angle Y + \angle Y = 360^{\circ}[/tex]
Take LCM
[tex]\frac{5\angle Y + 5\angle Y + 2\angle Y+ 2\angle Y}{2}= 360^{\circ}[/tex]
[tex]\frac{14\angle Y}{2}= 360^{\circ}[/tex]
Multiply both sides by [tex]\frac{2}{14}[/tex]
[tex]\frac{2}{14} * \frac{14\angle Y}{2}= 360^{\circ} * \frac{2}{14}[/tex]
[tex]\angle Y= 360^{\circ} * \frac{2}{14}[/tex]
[tex]\angle Y= \frac{ 360^{\circ} *2}{14}[/tex]
[tex]\angle Y= \frac{720^{\circ}}{14}[/tex]
[tex]\angle Y= 51.43 ^{\circ}[/tex]
So:
[tex]\angle G = \angle Y = 51.43 ^{\circ}[/tex]
[tex]\angle D = \frac{5}{2}\angle Y[/tex]
[tex]\angle D = \frac{5}{2} * 51.43^{\circ}[/tex]
[tex]\angle D = \frac{5* 51.43^{\circ}}{2}[/tex]
[tex]\angle D = \frac{257.15^{\circ}}{2}[/tex]
[tex]\angle D = 128.57 ^{\circ}[/tex]
Hence:
[tex]\angle D = \angle R = 128.57 ^{\circ}[/tex]

Simplify the expression -(6 - 4p)
Hey there!
The answer to your question is [tex]-6+4p[/tex]
Given:
[tex]-(6-4p)[/tex]
First, we distribute the negative sign to both terms ([tex]6[/tex] [tex]and[/tex] [tex]-4p[/tex]) This would make the [tex]6[/tex] negative and the [tex]-4p[/tex] positive, so we have:
[tex]-6[/tex] [tex]and[/tex] [tex]4p[/tex]
Add them together and we get:
[tex]-6+4p[/tex]

–19w + 11 = –17w − 19
w=
Please help, will mark brainliest to correct answer!
Answer:
w = 15
Step-by-step explanation:
We have an expression and are asked to solve for w.
-19w + 11 = -17w - 19
Subtract 11 from both sides :
-19w = -17w - 30
Add 17w to both sides :
-2w = -30
Divide -2 from both sides to isolate w :
w = 15
