Hi There,

An addition sentence with the sum of 20, is 10+10, this is the answer because if you add 10 to 10 you should get 20 which is the sum.

Hope This Helped :)

10+10=20, 15+5=20 Those are both addition sentences that have a sum of 20.

How to solve step by step 4(x-7)=-6x+12

nlexa [21]

Answer:

x = 3

Step-by-step explanation:

4 ( x - 7 ) = -6x + 12

→ Expand brackets

4x - 28 = -6x + 12

→ Add 6x to both sides

10x - 28 = 12

→ Add 28 to both sides

10x = 30

→ Divide both sides by 10

x = 3

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.
