Answer:
"Multiply –6 and 3"
Step-by-step explanation:
For order of operations, we follow the rule PEMDAS
- We do PARENTHESIS first, then
- Exponents, then
- Multiplication, then
- Division, then
- Addition, then
- Subtraction
In this problem, we have parenthesis, so (-6)(3) should be done first.
Hence, we should multiply -6 and 3.
m∠A + m∠B = 90
(3x + 5) + (2x - 15) = 90
(3x + 2x) + (5 - 15) = 90
5x - 10 = 90
+ 10 + 10
5x = 100
5 5
x = 20
m∠A = 3x + 5
m∠A = 3(20) + 5
m∠A = 60 + 5
m∠A = 65
m∠B = 2x - 15
m∠B = 2(20) - 15
m∠B = 40 - 15
m∠B = 25
the top numbers is the number you start on (on the bottom) then you go up (as the second number under it) in your case $ then you put a dot where they connect hope that helps!
Answer:
6:9
Step-by-step explanation:
the answer is 6:9 because 4:6' equivalent is 2:3, which is the same as 6:9
Answer:
x = 13
Step-by-step explanation:
This is a simple algebraic problem. Since x must be left by itself in order to solve, we subtract 10 on both sides, giving us the final answer of x = 13.
