Answer quickly for 5 star and brainliest.
1. what could you multiply the second (purple) equation by to make the y-values additive inverses? (see photo 1)
2. what could you multiply the top equation by to be able to add the equations and eliminate the x-values in this system? (see photo 2)

1. multiply by -2

2. multiply by 3

Step-by-step explanation:

1. 3x-4y=-5

5x-2y=-6

multiply the second equation by -2 to get 4y.

-10x+4y=-12

2. 2x+5y=5

-6x+7y=-37

multiply the top equation by 3 to get 6x

6x+15y=15

three-fourths of an hour

36÷48=0.75

0.75=

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
