From my research, the original system of equations contain the following equations:
<span>2x − y = −4
3x + 5y = 59
where obtained solution is x = 3
Among the choices, it is easier to substitute </span><span>3x + 5y = 59 with one of the choices to see if they yield the same solution set. From trial-and-error, the equation that can replace the original equation is " 13x = 39 ". Among the choices, it is the 4th choice.</span>
Answer:
1 adult cat
Step-by-step explanation:
<u>Thursday:</u>
The ratio of adult cat to kitten at a pet care center on Thursday was 4:3.

Answer:
The length of the steel frame will be approximately 44 feet
Step-by-step explanation:
We can solve this problem by calculating the circumference of the steel frame. We are working with the fact that the steel frame was welded into a circular shape.
The circumference of the steel frame can be calculated using

where d diameter of the steel frame = 14 feet

Therefore, the length of the steel frame will be approximately 44 feet
The answer is the first one if you dont believe me i calculated it <span />
Answer:
mAC=70°
Step-by-step explanation:
Someone can corroborate this but:
180°-110=70°=(m<aed)
180°-(m<aed)=70°
mAC=mBD
