Solve each equation. Show your work<br><br> 13a=-5<br> 12−b=12.5<br> -0.1=-10c
amid [387]
1) 13a=-5
Make a the subject of the formula by dividing both sides by 13(the coefficient of a)
13a/13=-5/13
Therefore a= -0.385

The second one). 12-b= 12.5
You take the 12 to the other side making b subject of the formula (-b in this case)
-b= 12.5-12
-b= 0.5
(You cannot leave b with a negative sign so you will divide both sides by -1 to cancel out the negative sign)

-b/-1= 0.5/-1
Therefore b=-0.5

The third one). -0.1= -10c
You will divide both sides by the coefficient of c(number next to c) which is -10
-0.1/-10= -10c/-10

Hence, c= 0.01

Which rules has a scale factor of 5 and shifted up and to the left?
serious [3.7K]

Answer:

185 37 = 5 1; the scale factor is 5: 1. So every other linear measure is multiplied times 5. If we have the big right triangle and want to scale it down to make the smaller one, we write this: 37 185 = 1 5

SUPER URGENT!!!!!!!! I NEED HELP!!!!!1 PLSSSS!!!!!Use the linear combination method to solve the system of equations. Explain ea
Vedmedyk [2.9K]

Answer:

x=-3,y=-2

Step-by-step explanation:

Given 2 expressions

S1:3x-8y=7

S2:x+2y=-7

Write one equation in terms of any variable (x or y)

Here I am writing S1 in terms of y

3x-8y=7\\3x-7=8y\\y=\frac{3x-7}{8}

Substitute this value of y as the value of y in S2

⇒x+2y=-7\\x+(\frac{3x-7}{8} )\times2=-7\\8x+6x-14=-56\\14x=-42\\x=-3

Therefore x=-3

Substitute this value of x in any of the expressions S1 or S2

Here i am substituting in S2

⇒x+2y=-7\\-3+2y=-7\\2y=(-7+3)\\2y=-4\\y=-2

Therefore x=-3 and y=-2
