Solve and check: 1 x + 3 = x + 10 x − 2 From least to greatest, the solutions are x = and x = .

blondinia [14]

Answer:

x= 1/2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

1x+3=x+10x−2

x+3=x+10x+−2

x+3=(x+10x)+(−2)(Combine Like Terms)

x+3=11x+−2

x+3=11x−2

Step 2: Subtract 11x from both sides.

x+3−11x=11x−2−11x

−10x+3=−2

Step 3: Subtract 3 from both sides.

−10x+3−3=−2−3

−10x=−5

Step 4: Divide both sides by -10.

−10x/−10=−5/−10x=1/2

Danielle earns a 8.25% commission on everything she sells at the electronics store where she works. She also earns a base salary

jeka94

Danielle earned $979.75 last week.

Step-by-step explanation:

Base salary = $625 per week

Commission = 8.25%

Cost of items sold = $4300

Amount of commission = $8.25\% \of \cost\ of\ sold\ items$

$Amount\ of\ commission=\frac{8.25}{100}*4300\\Amount\ of\ commission=\frac{35475}{100}\\Amount\ of\ commission=\$354.75$

Total earning last week = Base salary per week + amount of commission

$Total\ earning = 625+354.75\\Total\ earning=\$979.75$

Danielle earned $979.75 last week.

Complete the equation of variation where y varies inversely as x and y = 80 when x = 0.7.

andre [41]

Y varies inversely with x
means that y=k/x
with x=0.7 and y=80
we have 80=k/0.7
k=0.7x80=56
so the equation is
y=56/x

Help please I’m almost done

netineya [11]

Answer:

33 and -39

Step-by-step explanation:

Angle on a straight line = 180

|5x + 15| = 180 and |5x + 15| = -180

5x + 15 = 180

Subtract 15 from both sides;

5x = 165

Divide both sides by 5;

x = 33

5x + 15 = -180

Subtract 15 from both sides;

5x = -195

Divide both sides by 5;

x = -39
