Answer:
7
Step-by-step explanation:
3x- 1/9y = 18
value of x when y is 27
3x- 1/9*27 = 18
3x- 3 = 18
3x = 18 + 3
3x = 21
x= 21/3
x = 7
Hope this helps you!
Answer:
653
Step-by-step explanation:
The surface area of the larger cube is
2(10 x 7) + 2(12x7) + 2(10x12) = 140 + 168 + 240 = 548
The surface area of the smaller cube (minus the surface that is covered by the other figure)
4(8x3) + 1(3x3) = 96 + 9 = 105
105 + 548 = 653
Multiply the length and width together:
3 2 6
A = ------ * ------ = --------
5 5 25
None of the given possible answers make any sense. Please ensure that you have copied down this problem exactly as presented.
If the width were 2/5 in and the length 3/5 in, then, using decimal fractions, the area would be
A = 0.4(0.6) = 0.24 in^2, which is miles and miles away from 15 in^2 (for example)
Answer:
1
Step-by-step explanation:
f(g(x)) = 1, therefore the domain is 1
Answer:
Option 3, p(0) = -10
Option 4, p(10) = 0
Step-by-step explanation:
<u>Step 1: Check</u>
x - 10 + 10 = 0 + 10
<em>x = 10</em>
f(0) = 0 - 10 = -10
x = -10
<em>p(10) = 0</em>
Answer: Option 3, p(0) = -10, Option 4, p(10) = 0
