1)a-19=3 2) y/7=10 3)5g=100 solve please

1 answer:

6 0

Are these three different questions? if so:
1: add 19 to both sides to get a = 3 +19
answer: a = 22

2: multiply both sides by 7 to get y = 10 * 7
answer: y = 70

3: divide both sides by 5 to get g = 100/5
answer: g = 20

hope this helped! good luck :)

Answer:

Step-by-step explanation:

f(x) = 2x-1

g(x) =x^2 +3

f°g(x) = means put g(x) in for x into the function f(x)

f(g(x)) = 2 (g(x)-1

=2(x^2 +3) -1

Distribute

= 2x^2 +6-1

=2x^2 +5

Now we let x=-4

f(g(-4)) = 2 (-4)^2 +5

=2(16) +5

=32+5

=37

Megan will multiply the first equation by 3 then add the result to the second equation.

Nesterboy [21]

The resulting equation will be x + y = 4 and 4y =20

<h3>System of equation</h3>

GIven the system of equation given as:

x + y = 4

-3x + y = 8

If Megan multiplies the first equation by 3 then add the result to the second equation, the resulting equation will be:

3x + 3y = 12

-3x + y = 8

Adding both equation

3y + y = 12 + 8

4y = 20

Hence the resulting equation will be x + y = 4 and 4y =20

Jenny bought a wok for £9.60 in a 20% off sale. What was the price of the wok before the sale?

emmasim [6.3K]

Answer:

£12

Step-by-step explanation:

9.60 = 80% times y.

9.60 = 0.8y

Then, divide each side by 0.8 to get the equation in shape to solve for y.

y = 9.60/0.8

y=12
