Answer:

x=8

Step-by-step explanation:

48=5(2x-7)+3

Use the distributive property

48=10x-35+3

Combine like terms

48=10x-32

Add 32 to both sides to cancel out the negative 32

80=10x

x=8

Answer:

x = 8

Step-by-step explanation:

Step 1: Write equation

48 = 5(2x - 7) + 3

Step 2: Solve for x

Distribute 5: 48 = 10x - 35 + 3
Combine like terms: 48 = 10x - 32
Add 32 to both sides: 80 = 10x
Divide both sides by 10: 8 = x
Rewrite: x = 8

Step 3: Check

Plug in x to verify it's a solution.

48 = 5(2(8) - 7) + 3

48 = 5(16 - 7) + 3

48 = 5(9) + 3

48 = 45 + 3

48 = 48

Select the correct answer.

Crazy boy [7]

check the picture below.

now, if we split that triangle like so with that red line, we can use the right-triangle there, to get θ.

$\bf tan(\theta )=\cfrac{\stackrel{opposite}{3}}{\stackrel{adjacent}{3}}\implies tan(\theta )=1\implies tan^{-1}(\theta )=tan^{-1}(1)\implies \measuredangle \theta =\cfrac{\pi }{4}$

Make n the subject of the formula

kogti [31]

Answer:

$\mathsf{ \frac{m + 21}{5} = n }$

Step-by-step explanation:

To make "n" the subject of the formula, rearrange the formula so it begins with " n = "

To isolate the variable "n", you need to inverse the other terms on that side of the equation where "n" really is.

=> m = 5n - 21

there's a "-21" next to "5n", inverse of subtraction is addition, so add 21 on both sides of the equation.

=> m + 21 = 5n - 21 + 21

=> m+ 21 = 5n

There's also a 5 attached to n, that means the multiplication of n with 5, the inverse of multiplication is division, so dividing both sides of the equation by 5

$\mathsf{ \frac{m + 21}{5} = n }$
