Solve 2(x - 5) = 3(x + 7)
Answer:
x = -31
Step-by-step explanation:
2(x-5) = 3(x+7) 1. Use distributive property
2x - 10 = 3x + 21 2. Add 10 on both sides
2x = 3x + 31 3. Subtract 3x on both sides
-x = 31 4. Divide by -1
x = -31

find the domain and range of the function represented by the graph.
Answer:
C
Step-by-step explanation:
The domain of this function is [tex][-4,2][/tex], as it is shown in the graph that [tex]x[/tex] is only within this interval. The range of this function is [tex][-4,4][/tex], as the smallest value of [tex]y[/tex] is -4 and the largest value of [tex]y[/tex] is 4, and [tex]y[/tex] takes every possible values between them.

does 9/20 and 18/30 form a proportion
Answer:
No, they don't.
Step-by-step explanation:
I'm going to divide 18 by 9 and 30 by 20. If the quotients are the same, then we do have a proportion.
18 ÷ 9 = 2
30 ÷ 20 = 1.5
The quotients aren't the same. Same thing if you convert the fractions to decimals:
9 ÷ 20 = 0.45
18 ÷ 30 = 0.6
This means the two values do NOT form a proportion.
Hope this helps! Have a great day!
Answer:
No.
Step-by-step explanation:
9/20=18/30
9*30=20*18
120=360

2. Four big water bottles can hold 8 gallons of water. How much water can ten big water bottles
hold?
Answer:
16 1/2 gallons of water.
Step-by-step explanation:
Since 4 bottles can hold 8 gallons, and you need to know how much 10 can hold, you can multiply 4 and 8 times 2 so you get 8 and 16, and then if you choose 10 instead of 8 instead you would get the result of 10 bottles being able to hold 16 1/2 gallons of water.
I hope this helps you :D
14d - 22 + 5d = 12d - 8
Answer:
d = 2
Step-by-step explanation:
14d - 22 +5d = 12d - 8
19d -22 = 12d - 8
+22 +22
19d = 12d + 14
-12d -12d
7d = 14
/7 /7
d = 2
Answer:
d = 2
Step-by-step explanation:
Simplifying
14d + -22 + 5d = 12d + -8
Reorder the terms:
-22 + 14d + 5d = 12d + -8
Combine like terms: 14d + 5d = 19d
-22 + 19d = 12d + -8
Reorder the terms:
-22 + 19d = -8 + 12d
Solving
-22 + 19d = -8 + 12d
Solving for variable 'd'.
Move all terms containing d to the left, all other terms to the right.
Add '-12d' to each side of the equation.
-22 + 19d + -12d = -8 + 12d + -12d
Combine like terms: 19d + -12d = 7d
-22 + 7d = -8 + 12d + -12d
Combine like terms: 12d + -12d = 0
-22 + 7d = -8 + 0
-22 + 7d = -8
Add '22' to each side of the equation.
-22 + 22 + 7d = -8 + 22
Combine like terms: -22 + 22 = 0
0 + 7d = -8 + 22
7d = -8 + 22
Combine like terms: -8 + 22 = 14
7d = 14
Divide each side by '7'.
d = 2
Simplifying
d = 2

Aldo's scores on four tests are 88, 85, 100, and 86. What must the score be on the fifth test for her average to be 90?
x=5th test score
(88+85+100+86+x)/5=90
(359+x)/5=90
71.8+x/5=90
-71.8 -71.8
x/5=18.2
*5 *5
x=91
the fith test score has to be 91 in order for the average to be 90

Events A and B are such that P(A) = 3 8 , P(B) = 2 7 and P(A ∩ B) = 1 7 Work out P(A|B)
Answer:
[tex]\frac{17}{27}[/tex]
Step-by-step explanation:
Given: Events A and B are such that [tex]P(A)=38\,,\,P(B)=27[/tex] and P(A∩B) = 17
To find: [tex]P(A|B)[/tex]
Solution:
Probability refers to the chances of occurrence of any event.
An event is described as an outcome of a random experiment.
A random experiment is an experiment for which outcomes cannot be predicted.
[tex]P(A|B)=[/tex] P(A∩B) ÷ P(B) = [tex]\frac{17}{27}[/tex]

Answer:
c (6)
Step-by-step explanation:
by the corresponding angles postulate, the angle above 20x-5 will be 65°.
20x - 5 + 65 = 180 they are supplementary angles (angles that add up to 180°)
20x + 60 = 180
20x = 120
x = 6
