The value in cents of 4 quarters and x dimes is

1 answer:

4 0

To add numbers, their units should be the same. We need first to convert the quarters and dimes into cents.
4 quarters is equal to 100 cents, while a dime is equal to 10 cents.
In formula, the answer would be 100+10x. ( x refers to the number of dimes)

3.9x + 1.4 = 17 what is the steps

Vedmedyk [2.9K]

Answer:

$x=4$

Step-by-step explanation:

$3.9x + 1.4 = 17$

Having a decimal is not very nice to deal with, so we multiply all sides by 10 to get rid of the decimals.

$3.9x*10+1.4*10=17*10$

$39x+14=170$

Subtract 14 from both sides:

$39x+14-14=170-14$

$39x=156$

Divide both sides by 39:

$\frac{39x}{39}=\frac{156}{39}$

$x=4$

Solve for x then find the measure of the angle given

ololo11 [35]

Answer:

∠ MPQ = 125°

Step-by-step explanation:

∠ LMN and ∠ MPQ are corresponding angles and are congruent , so

5x = 3x + 50 ( subtract 3x from both sides )

2x = 50 ( divide both sides by 2 )

x = 25

Then

∠ MPQ = 3x + 50 = 3(25) + 50 = 75 + 50 = 125°

What are the values of m and n?

snow_lady [41]

180 - 138 = 42°
90 + 42 = 132°
180 - 132 = 42° = m
-
90 + 42 + 2n = 180
132 + 2n = 180
- 132
2n = 48
÷ 2
n = 24°
-
Hope this helps! Let me know if you have any questions :)

Solve the following inequality. 36> -2(x+4)+14

Jet001 [13]

Answer:

x > - 15

Step-by-step explanation:

Given

36 > - 2(x + 4) + 14 ← distribute and simplify right side

36 > - 2x - 8 + 14

36 > - 2x + 6 ( add 2x to both sides )

2x + 36 > 6 ( subtract 36 from both sides )

2x > - 30 ( divide both sides by 2 )

x > - 15
