which equation can replace 3x 5y = 59 in the original system and still produce the same solution? 2x – y = –4 10x – 5y = –20 7x

natka813 [3]

From my research, the original system of equations contain the following equations:

2x − y = −4
3x + 5y = 59

where obtained solution is x = 3

Among the choices, it is easier to substitute 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.

emmainna [20.7K]

Answer:

1 adult cat

Step-by-step explanation:

Thursday:

The ratio of adult cat to kitten at a pet care center on Thursday was 4:3.

Number of adult cats = 4x

Number of kitten cats = 3x

There were 12 kittens, then

$3x=12\\ \\x=\dfrac{12}{3}\\ \\x=4\\ \\4x=4\cdot 4=16$

There were 16 adult cats

Tuesday:

17 adult cats were at the pet care center.

Difference:

$17-16=1$ adult cat

At a school carnival is the diameter of the map of a trampoline has 12 feet and the diameter of the metal frame is 14 feet what

Lisa [10]

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

$circumference = \pi \times d$

where d diameter of the steel frame = 14 feet

$circumference = 3.14 \times 14=43.96ft$

Therefore, the length of the steel frame will be approximately 44 feet

6. In the circle below, chords AB and CD intersect at E. If mBD = 70° and mZAEC = 110° , find mAC

Kitty [74]

Answer:

mAC=70°

Step-by-step explanation:

Someone can corroborate this but:

180°-110=70°=(m<aed)

180°-(m<aed)=70°

mAC=mBD
