A number p is greater than or equal to –17.
How do I find the answer?
Answers
Answer:
You're answer has be written as an inequality, therefore it would be;
=> p ≥ -17
Hope this helps!
Answer:
p is less than -17
Step-by-step explanation:
The inequality that can be used for this is p+5 <17. The reason is because you have to read the question very carefully. They try to trick you. I would underline five more than a number p is less than 17. This helps you because now when you think of 5 more than you think of addition. Which would be p+5. Then, this number is less than 17. So it would be p+5<17. For the solution, you would subtract 5 from both sides. Why? That way it frees up and you are left with p. Since that is all you want. Then, once you do that your solution should be p<12. Since that is what you will be left with.

(6x + 3)
(x + 12.5)°
(2x + 8)
Answers
Answer:
x = 23.5
Step-by-step explanation:
For a trapezoid, the angles on the same side are supplementary. This simply mean they add up to 180 degrees
thus, we have it that;
(6x + 3) + (x + 12.5) = 180
6x + x + 3 + 12.5 = 180
7x + 15.5 = 180
7x = 180-15.5
7x = 164.5
x = 164.5/7
x = 23.5

2)solve the measure of rq
3)solve the measure of pq
4)solve the measure of pr
5)solve the measure of pqsr
Answers
Answer:
See solutions below
Step-by-step explanation:
1) From the diagram QS = RS
3x = 2x+2
3x-2x = 2
x = 2
Since RS = 2x+2
RS = 2(2)+2
RS = 4 + 2
RS = 6
2) RQ = RS + QS
RQ = 2x+2 + 3x
RQ = 5x+2
RQ = 5(2)+2
RQ = 12
3) PQ = PR
3y-1 = y+5
3y-y = 5+1
2y = 6
y = 3
PQ = 3y-1
PQ = 3(3)-1
PQ = 8
4) PR = y+5
PR = 3+5
PR = 8
5) PQSR = PQ + QR
PQSR = 8 + 12
PQSR= 20
The estimated total,costs,y, of a child's toy is practally based on the number of batteries used x.The cost of one battery is 0.75. The toy itself cost 12$.Which equation represents the situation
Answers
Answer:
y = 0.75x + 12
Step-by-step explanation:
The estimated total cost, y, of a child's toy is partially based on the number 1 point of batteries used, x. The cost of one battery is $0.75. The toy itself costs $12. Which equation represents the situation?
y = 12x + 0.75
y = 0.75x + 12
y = 12x − (775
y = 0.75x − 12
y = total cost of a child's toy
Cost of each battery = $0.75
Number of batteries = x
Cost of the toy = $12
Therefore,
total cost of a child's toy = Cost of the toy + Cost of each battery * Number of batteries
y = 12 + 0.75 * x
y = 12 + 0.75x
y = 0.75x + 12

From the remainder theorem, if we the divisor to zero and get a value for the variable, then substitute this value into the polynomial, the result we have is the remainder
So;
set x + 1 = 0 ; and x = -1
substitute this into the polynomial
(-1)^3 + 2(-1)^2 -5(a)(-1) -7
= -1 + 2 + 5a -7 = 5a -6
For the second;
set x -2 = 0; x = 2
Substitute in the second polynomial;
2^3 + a(2)^2 -12(2) + 6
= 8 + 4a -24 + 6 = 4a -10
So therefore;
2(5a-6) + 4a - 10 = 6
10a-12 + 4a -10 = 6
10a + 4a -22 = 6
14a = 6 + 22
14a = 28
a = 28/14
a = 2

Step-by-step explanation:
Wanda spends a third of her [tex]4\frac{1}{8}[/tex] hours studying math. Let us multiply these two fractions to find how much time she spent. Our first step would be to convert the mixed number into an improper fraction, as mixed numbers are hard to manipulate with:
[tex]4\frac{1}{8} =\\\frac{33}{8}[/tex]
Now let us multiply:
[tex]\frac{1}{3} *\frac{33}{8} =\\\frac{11}{8}[/tex]
If we wish, we can convert this into a mixed number:
[tex]\frac{11}{8}= \\1\frac{3}{8}[/tex]
or, 1 hour and 22.5 minutes.
Therefore, Wanda spent [tex]1\frac{3}{8}[/tex] hours, or 1 hour and 22.5 minutes studying math.
