Answer:
(6,-6)
Step-by-step explanation:
1. -10x-15y=30
-10x-15y+15y=30+15y
-10x/-10=30+15y/-10
x=-3 -3/2
plug in the other equation and solve for y
-9x-5y=-24
-9(-3-3/2)-5y=-24
y=-6
plug -6 in for y in one of the original equations
-9x-5y=-24
-9x-5(-6)=-24
solve for x
x=6
<em>wonderful</em>
Answer:
1/4 inch
Step-by-step explanation:
Multiply 1x1 to find the area
Divide by 4 to get 1/4.
OR
Multiply 1/2 x 1/2 to get the same answer
Order of Operations, also known as PEMDAS (Parentheses, Exponents, Multiplication & Division, Addition & Subtraction), can help to simplify an equation by guiding you through the steps to solve it.
This is because it tells you to solve the parentheses. If there is none, but you've already done this, you solve for exponents, etc.
The progressive soling of the equation not only makes it physically shorter, but also brings you closer to the answer.
Hope this helps, and I was the brainliest! :)
One idea is:
Paul wants to buy an iphone X. He has savings of $100 to start with. Local McDonalds pays $7 per hour (after tax) to students on summer break for helping out at the counter. The iphone costs $1000. At least how many hours does Paul need to work at McDonalds to be able to afford the iphone.
So, that matches ax+b>c in that
a is the hourly earning
b is the initial savings
c is the price of the iphone
