Solve the equation. Check your answers.29=7x+5-4x​

Mathematics
1 answer:
Vladimir [108]3 years ago
6 0

Answer:

x = 8

Step-by-step explanation:

29=7x + 5 -4x

add like terms: 29 = 3x +5

get your x variable on one side

24 = 3x

divide by 3

x = 8

check!

29 = 7(8) + 5 -4(8)

29 = 56 + 5 -32

29 = 51 - 32

29 = 29

Leo, Kush and Mai share some money in the ratio 3:5:8
Marta_Voda [28]

Answer:

The total amount of money that they shared is \£6,000

Step-by-step explanation:

Let

x-----> amount of money Leo shares

y-----> amount of money Kush shares

z-----> amount of money Mai shares

we know that

\frac{x}{y} =\frac{3}{5}

x=\frac{3}{5}y -----> equation A

\frac{y}{z} =\frac{5}{8}

z=\frac{8}{5}y -----> equation B

\frac{x}{z} =\frac{3}{8}

z=\frac{8}{3}x -----> equation C

y=x+750 ------> equation D

substitute equation A in equation D and solve for y

y=\frac{3}{5}y+750

y-\frac{3}{5}y=750

\frac{2}{5}y=750

y=750*5/2=\£1,875

Find the value of x (equation A)

x=\frac{3}{5}(1,875)=\£1,125

Find the value of z (equation C)

z=\frac{8}{3}(1,125)=\£3,000

therefore

The total amount of money is equal to

x+y+z=\£1,125+\£1,875+\£3,000=\£6,000

(a) (4,4) is a point on a locus whose equation is y2 = kx. Show that (16,8) is another point on the locus.
Vlad [161]

Step-by-step explanation:

plug the coordinate points into the equations and solve for the remaining variable.

b) (2,3) - 5(2) + b(3) = 16

10 + 3b = 16. 3b= 6. b = 2

(0,8) - 5(0) + 2(8) = 16. 0+ 16 = 16. ☆

a) (4,4) assume based on results you meant y squared. (y^2)

(4)^2 = 4k. 16 = 4k. k = 4

(8)^2 = 4(16). 64 = 64. ☆
