stich3 [128]3 years ago
4 0

Answer:

<h2>x = 1</h2>

Step-by-step explanation:

-2+4(-x+4)=10\qquad\text{use the distributive property:}\ a(b+c)=ab+ac\\\\-2+(4)(-x)+(4)(4)=10\\\\-2-4x+16=10\qquad\text{combine like terms}\\\\-4x+(-2+16)=10\\\\-4x+14=10\qquad\text{subtract 14 from both sides}\\\\-4x+14-14=10-14\\\\-4x=-4\qquad\text{divide both sides by (-4)}\\\\\dfrac{-4x}{-4}=\dfrac{-4}{-4}\\\\x=1

Mrquis ran 1/2 mile, Chad ran 7/8 mile, Jose ran 3/5 mile, and stephen ran 3/4 mile. Order them greatest to least
postnew [5]

Answer: Chad, Stephen, Jose and Mrquis

Step-by-step explanation:

We can change them to Percentage to make their ordering easier.

Mrquis ran 1/2 mile = 1/2 × 100 = 50%

Chad ran 7/8 mile = 7/8 × 100 = 87.5%

Jose ran 3/5 mile = 3/5 × 100 = 60%

Stephen ran 3/4 mile = 3/4 × 100 = 75%

Therefore, the ordering from the greatest to the least will be:

Chad, Stephen, Jose and Mrquis

The cash price of a gas stove was X ringgit. Roy bought the stove by making a RM100 down payment and the balance was settled by
alina1380 [7]

Answer:

a) The cash price of the gas stove was 1300 ringgit

b) The original unpaid balance = 1200 ringgit

The original unpaid balance including interest =  1320 ringgit

Step-by-step explanation:

Given:

Cash price of the gas stove = X ringgit

Down payment = RM100

Total monthly payments = 24

Each payment = RM55

Interest rate charged = 10%

now,

After down payment,

Remaining balance = RM(X - 100)

Balance after interest = RM(X - 100) × ( 1 + r)

= RM(X - 100) × ( 1 + 0.1)

= RM(1.1X - 110)

also,

amount paid in total installments

= 24 × RM55

= RM1,320

and,

RM1,320 = RM(1.1X - 110)

or

1.1X = 1,430

or

X = 1300

Hence,

a) The cash price of the gas stove was 1300 ringgit

b) The original unpaid balance = X - 100

= 1300 - 100

= 1200 ringgit

and,

after including interest

The original unpaid balance = 1.1(X - 100)

= 1.1 × (1300 - 100)

= 1320 ringgit
