B) 
In order to eliminate 
we need to multiply 
to equation B and add it to A.
Multiplying to B.
⇒ 
⇒ 
⇒ 
Adding it equation A.
+ 
We get 
Thus is eliminated.
So, the expression used to eliminate is:
Answer:
Step-by-step explanation:
5x+2x+7=7x+7
Answer:
False
Step-by-step:
The hypotenuse of the triangle is the side opposite to the right angle. The legs are the other two sides of the triangle. Since AC is on the opposite side of the right angle, it is the hypotenuse and therefore not a leg. Hope this helps!
Yes, we claim that the two ratios are proportional.
<h3>Proportion</h3>
Proportion is an equality between two ratios. These ratios are made up of two real integers. In a proportion, when there is an equality, both ratios have to be equivalent to the other. Equivalent ratio is when both division results are equal.
— To find out if the equality between these two given ratios is true, let's just: divide the numerator by the denominator.
3/8 = 3 ÷ 8 = <u>0,375</u>
24/64 = 24 ÷ 64 = <u>0,375</u>
Therefore, we see that the results of these ratios are the same. So these two ratios are proportional. 3/8 = 24/64
Answer: 17 square inches.
Step-by-step explanation: Area of a triangle is 1/2 x b x h. We can just take the area of half of the whole triangle, and double it. In this case, half of the triangle has an area of 1/2 x 3.4 x 5 = 8.5. Doubling it is the same is doing 8.5 x 2, which equals 17.
