What are all the solutions to the following<br> equation?<br> |10x + 2| =48

Greeley [361]

$\huge \boxed{\mathfrak{Question} \downarrow}$

What are all the solutions to the following

equation?

|10x + 2| =48

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

$| 10 x + 2 | = 48$

Combine like terms and use the properties of equality to get the variable on one side of the equals sign and the numbers on the other side. Remember to follow the order of operations.

$|10x+2|=48$

Use the definition of absolute value.

$10x+2=48 \\ 10x+2=-48$

Subtract 2 from both sides of the equation.

$10x=46 \\ 10x=-50$

Divide both sides by 10.

$\boxed{ \boxed{ \bf \: x=\frac{23}{5} = 46}} \\ \boxed{\boxed{ \bf \: x=-5 }}$

Which expression is equivalent to (21/2 x 2 3/4)^2

sasho [114]

ANSWER

$(2 \frac{1}{2} \times 2 \frac{3}{4} ) ^{2} = 47 \frac{17}{64}$

EXPLANATION

To find the expression that is equivalent to
$(2 \frac{1}{2} \times 2 \frac{3}{4} ) ^{2}$

we need to simplify it.

We convert the mixed numbers to improper fraction as follows.

$(2 \frac{1}{2} \times 2 \frac{3}{4} ) ^{2} = ( \frac{2 \times 2 + 1}{2} \times \frac{2 \times 4 + 3}{4} ) ^{2}$

This will give us,

$(2 \frac{1}{2} \times 2 \frac{3}{4} ) ^{2} = ( \frac{4 + 1}{2} \times \frac{8 + 3}{4} )^{2}$

$(2 \frac{1}{2} \times 2 \frac{3}{4} ) ^{2} = ( \frac{5}{2} \times \frac{11}{4} )^{2}$

We multiply the expression in the parenthesis on the right hand side to obtain,

$(2 \frac{1}{2} \times 2 \frac{3}{4} ) ^{2} = ( \frac{55}{8} )^{2}$

We share the exponent for the numerator and the denominator separately.

$(2 \frac{1}{2} \times 2 \frac{3}{4} ) ^{2} = \frac{ {55}^{2} }{ {8}^{2} }$

This simplifies to,

$(2 \frac{1}{2} \times 2 \frac{3}{4} ) ^{2} = \frac{ {3025} }{ {64}}$

We write the final answer as a mixed number to obtain,

$(2 \frac{1}{2} \times 2 \frac{3}{4} ) ^{2} = 47 \frac{17}{64}$

what number is 11 less than the other number if there's some is increased by 8 the result is 71 find the numbers

Keith_Richards [23]

Answer:

26,37

Step-by-step explanation:

m=n-11

m-n=-11-------(1)

m+n+8=71--------(2)

(1)+(2)

(m-n)+(m+n+8)=-11+71

m-n+m+n+8=-11+71

2m+8=60

2m=52

m=26

by substitute in (1)

26-n=-11

-n=-11-26

n=37
