Answer: x < -1
Step-by-step explanation:
x + 6 < 5
x + 6 = 5
x = -1
x < -1
Now try to prove its correct
A number less than -1 is -2 so we'll try that.
x + 6 < 5
(-2) + 6 < 5
4 < 5
We can tell after substituting -2 for x, that the answer is correct
Oh and I changed the less than sign to an equal sign so it's easier to solve.
Does that help?

Your answer should be a polynomial in standard form.
(9+ m)(-m +9)=
Answer: -1m²+81
Step-by-step explanation:
correct standard form means that the terms are ordered from biggest exponent to lowest exponent.The leading coefficient is the coefficient
of the first term in a polynomial in standard form.
FoR example, (9+ m) (-m+9) = *(m+9) (-m+9) *m(-m+9) +9 (-m+9)* -1.mm+9m +9(-m+9) * -1m² +9m +9(-m+9) *-1m²+9m- 9m +81
answer -1m²+81

Felix worked at a music shop during the summer. The table below shows some of Felix’s hours and earnings. The amount of money he earned is proportional to the number of hours he worked.
2. Let x represent the number of hours he worked, y represents the amount of money he earned.Write an equation that represents this relationship.
3. If Felix worked 180 hours, then how much money did he earn?
Answer:
2. y=9x
3. 180*9 = 1620
Step-by-step explanation:
2. y = mx+b, so find the slop efirst
lacampanella avatar
so take the first two points you got
lacampanella avatar
(2,18) and (5,45),
lacampanella avatar
(45-18)/(5-2) = 9
lacampanella avatar
then use (2,18)
lacampanella avatar
18= 9*2+b
lacampanella avatar
so b=0
3. y = 9x
x= 180. y = 9*180 = 1620
The ratio of children to adults in a supermarket is 1 : 5
There are 15 children in the supermarket.
How many adults are in the supermarket?
pls answer quickly thanks :)
Answer: There are 75 Adults in the supermarket ask me why if you want a full on explanation. The full on reason of why it is 75 is because if you have a ratio of 1:5 and you now the one is for the kids and it is 15. Then you add 15 from 1 until you get to the 5th ratio. Hence, it brings you all the way to 75 adults. I hope this helped you, and anyone else

complete the equation 4/5= ____×
1/5
Answer:
HI! I think the answer is 4.
Answer:
4/5 = 4 x 1/5
Step-by-step explanation:
Since we can write 4 as 4/1, that means 4 is the answer. This is because you multiply the top numbers and the bottom numbers, 4x1 is 4, and 1x5 is 5, so that means the answer is 4 since that problem got us 4/5.

XY zand ABC are similar. If angle X is 32 degrees and angle Y is 84
degrees, find the measure of angle C.
Answer:
B
Step-by-step explanation:
A triangle always has a degree total of 180. x+y=116 180-116=64 therefore the last angle, angle c, must be 64 degrees.
Answer: B. 64 degrees
Step-by-step explanation:
∠C = 180° - (∠X + ∠Y)
∠C = 180° - (32° + 84°) = 180° - 116° = 64°

Answer:
it’s either no slope or 0, I dont exactly know which one you would put in to be correct
Step-by-step explanation:
The cost of renting a boat at a lake is $35 per hour plus $5 for life jackets. Write an
• equation in slope-intercept form that can be used to calculate the total amount you would pay for
renting a boat. (assume only you need a life jacket)
Answer:
y = 35x + 5
Step-by-step explanation:
Slope-intercept form is y = mx + b
m is the slope, b is the constant, or y-intercept.
In this case, 5 is our constant. You pay a one-time fee of $5 for a life jacket. This price doesn't change nor do you have to pay it again, so this is your constant.
35 is our slope. 35 represents the $35 you pay for each hour with the boat. This is our slope because it will change overtime, based on x, or the number of hours you are renting the boat.
y is the total cost, since you have to add up $35 times the number of hours you are renting, plus the $5 for the life jacket.

Find x.
Side splitter theorem
Answer:
x = 9
Step-by-step explanation:
The outer and inner triangles are similar, thus the ratios of corresponding sides are equal, that is
[tex]\frac{8}{8+4}[/tex] = [tex]\frac{x-3}{x}[/tex] , that is
[tex]\frac{8}{12}[/tex] = [tex]\frac{x-3}{x}[/tex] ( cross- multiply )
12(x - 3) = 8x
12x - 36 = 8x ( subtract 8x from both sides )
4x - 36 = 0 ( add 36 to both sides )
4x = 36 ( divide both sides by 4 )
x = 9

WILL MARK BRAINLIEST TO THE BEST ANSWERS. The interior angles of a pentagon measure x°, (2x)°, (2.5x)° , (x + 10)° , and (2x + 20)°. Determine the value of x. PLEASE SHOW ALL SOLUTIONS NESSICARY. THANK YOU.......
Answer:
x=60
Step-by-step explanation:
The sum of interior angles of a regular Pentagon is 540°
x+2x+2.5x+x+10+2x+20=540
8.5x=540-30
8.5x=510
x=510/8.5=60
Answer:
x = 60°Step-by-step explanation:
Sum of interior angles of a regular polygon is:
180°(n-2)Pentagon has 5 sides, so sum of angles is:
180°(5-2) = 180°*3 = 540°For the given pentagon we have sum of angle measures as below, and solving for x:
x + 2x + 2.5x + (x +10) + (2x + 20) = 540°8.5x + 30° = 540°8.5x = 510°x = 510°/8.5x = 60°help with this .........

Answer:
SQT = 100
Step-by-step explanation:
A full circle equals 360 degrees, when the other angles are added up 140 + 120 = 260 which is 100 off of 360 meaning the last angle is that 100 degrees.
Describe and correct the error in using properties of parallelograms.
Answer/Step-by-step explanation:
Opposite angles of a parallelogram are equal to each other.
Therefore, <S = <U, and <T = <V
Consecutive angles of a parallelogram are supplementary.
Therefore,
m<S + m<V = 180°
50° + m<V = 180°
m<V = 180° - 50° (subtraction property of equality)
m<V = 130°
Three friends go grocery shopping together, and each guys the same kinds of strawberries. Akio buys 2 pounds and pays 1.50. Gordon buys 3 pounds and pays 2.25. Maria buys 4 pounds and pays 3.00.
Answer: Graph B
Step-by-step explanation:
The unit price for the strawberries is:
= 1.5 / 2
= $0.75 per pound
Graph B is the right graph as it uses a unit price of $0.75 per pound for strawberry price. This is why it has points of the graph that mirror the friends purchases such as (2, 1.5) , (3, 2.5) and (4, 3).
