Help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer:

subtract 7

Step-by-step explanation:

y+7=18

You need to get the y by itself, so you subtract 7 to cancel it out.

y+7=18

 -7   -7

y=11

30

I DONT KNOW BUT THAT'S MY ANSWER HOPE IT HELP

Step-by-step explanation:

Is it +30 or - 30

If it was -ve under root it will be complex or imaginary number but it is a easy question

Answer:

x= 3 and -1

Step-by-step explanation:

[tex]f(x) = {x}^{2} - 2x - 3[/tex]

add three to both sides

[tex]3 = {x}^{2} - 2x[/tex]

figure out what half of -2 is

half of -2 is (-1) than square that (-1)^2=1

the 1 is what you add to both sides

[tex]3 + 1 = {x}^{2} - 2x + 1 \\ 4 = {(x - 1)}^{2} [/tex]

than take the square root of both sides

[tex] \sqrt{4} = \sqrt{ {(x - 1)}^{2} } [/tex]

this than equals

+2=x-1

than to find the x values

2=x-1

+1 +1

3=x

-2=x-1

+1 +1

-1=x

Answer:

nre, nre

Step-by-step explanation:

Given

[tex]4b^2 + 16 = 0[/tex]

Required

Solve

[tex]4b^2 + 16 = 0[/tex]

Subtract 16 from both sides

[tex]4b^2 +16 -16 = 0 - 16[/tex]

[tex]4b^2 = - 16[/tex]

Divide both sides by 4

[tex]b^2 = -4[/tex]

Take square roots of both sides

[tex]b = \sqrt{-4[/tex]

[tex]\sqrt{-4} \to[/tex] Complex number

Hence, no real root exist

Step-by-step explanation:

Volume of the solid = base x width x height = 36 x 36 x 24 = 31 104 in^3

Volume of one prism = total volume / 12 = 31 104 / 12 = 2592 in^3

Answer:

a=18.7 or 19 rounded up

Step-by-step explanation:

83.6 pounds

Step-by-step explanation:

1 kg = 2.2 pounds

38 x 2 = 76

.2 x 38 = 7.6

76 + 7.6 is 83.6

Answer:

83.6 pounds

Step-by-step explanation:

1 kg = 2.2 pounds

38 x 2 = 76

.2 x 38 = 7.6

76 + 7.6 is 83.6

Jane's monthly payment this year using balance billing would be $164 per month.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

To determine Jane's monthly payment this year using balance billing, we need to divide the total amount she spent last year ($1,968) by the number of months in a year.

Total amount spent last year = $1,968

Number of months in a year = 12

So, Monthly payment = Total amount spent last year / Number of months in a year

Monthly payment = $1,968 / 12

Monthly payment ≈ $164

Therefore, Jane's monthly payment this year using balance billing would be $164 per month.

Answer:

15/10, 30/20, 60/40, 120/80, 240/160, 480/320

Step-by-step explanation:

The number of push-ups is 2/3 the amount of sit-ups, so the ratio of sit-ups to push-ups is 3:2.

The easy way to do this is to double both 15 and 10 so your answer will stay an equivalent ratio. You will always have a 3:2 ratio this way.

Answer:

x= 9

y= 3 root 3

Step-by-step explanation:

to find the shorter leg length you have: hypotenuse/2

[tex] \frac{6 \sqrt{3} }{2} = 3 \sqrt{3} [/tex]

to find the longer leg length you have: shorter leg × root 3

[tex]3 \sqrt{3} \times \sqrt{3} = 3 \sqrt{9 } = 3(3) = 9[/tex]

Answer:

Steps:

to solve this problem we have to calculate the surface area of the whole block and let be SA

first the surface area of the square pyramid:

the area of one triangle = (height × base)/2

given:

height = 6 cm

base = 4 cm

A = (6×4)/2

A = 24/2

A = 12 cm²

since it's a square triangle

then the surface area of the pyramid excluding the base:

Ap = A × 4

Ap = 12 × 4

Ap = 48 cm²

now the inferior part which is a rectangular prisme

Ar = 4(height×lenght)+lenght²

Ar = 4(3×4)+4²

Ar = 4×12+16

Ar = 48+16

Ar = 64 cm²

and now we can calculate the surface area of the whole block

SA = Ap + Ar

SA = 48 + 64

SA = 112 cm²
