Answer:
true
Step-by-step explanation:
2^31
use the rule that states the product of the same base with different powers you add them
(a^n) times (a^m) = a^(n+m)
50 states, 4 start with W (Washington, West Virgina, Wisconsin, Wyoming)
So its 8%
<h3><u>The value of the larger number, x, is 57.</u></h3><h3><u>The value of the smaller number, y, is equal to 42.</u></h3>
x - y = 15
2x + 8 = 3y - 4
We can quickly get a temporary value for x by altering the original equation.
x - y = 15
<em><u>Add y to both sides.</u></em>
x = 15 + y
Now that we have a value of x, we can find the exact value of y.
2(15 + y) + 8 = 3y - 4
<em><u>Distributive property.</u></em>
30 + 2y + 8 = 3y - 4
<em><u>Combine like terms.</u></em>
38 + 2y = 3y - 4
<em><u>Subtract 2y from both sides.</u></em>
38 = y - 4
<em><u>Add 4 to both sides.</u></em>
y = 42
Now that we know the exact value of y, we can plug it back into the original equation.
x - 42 = 15
<em><u>Add 42 to both sides.</u></em>
x = 57
Step-by-step explanation:
We'll use BODMAS to solve this
Open the brackets :
- 2(5x+5)+9(x-10)+9sq = 10x+10+9x-90+81
- Then we arrange them accordingly :10x+9x+10-90+81
- We then calculate :19x+10-90+81
- BODMAS :19x+91-90 = 19x+1
- ANSWER :19x+1
