Step-by-step explanation:
Write a proportion.
5 / 8 = 6 / x
Cross multiply.
5x = 48
Divide.
x = 9.6
She will need 9.6 ounces of blue paint.
The average of 4, 9, 16, 25 and x is 2x means that;
(4+9+16+25+x)/5=2x
Multiply both side by 5
5(54+x)/5=2x(5)
54+x=10x
Subtract x to both side
54+x-x=10x-x
54=9x
Divided 9 to both side
54/9=9x/9
x=6
Check:
Substitute x with 6
(4+9+16+25+x)/5=2x
(4+9+16+25+6)/5=2(6)
60/5=12
12=12; so x=6 which marks B as the correct answer. Have a nice day!
1. Commutative property of multiplication
IM SO SORRY IF IM WRONG
Answer:
B
Step-by-step explanation:
supplementary angles =180 degrees
180-117=63
Answer:
True
Step-by-step explanation:
The negative linear relationship means that there is inverse relationship between two variables. It means that if the independent variable increases the dependent variable decreases and if the independent decreases the dependent variable increases. It means that due to larger values of independent variable there occurs the smaller values for dependent variable.
