If -13x-71=201 what is x

Mathematics
1 answer:
jenyasd209 [6]3 years ago
6 0

Answer:

272/-13 or −20.923

Step-by-step explanation:

To solve this equation you need to isolate the variable.

First, add 71 to both sides

-13x-71+71=201+71

-13x=272

Then, divide both sides by -13

-13x/-13=272/-13

So, x=272/-13 or −20.923

Find the quotient of 4/7 and 2/4
iren [92.7K]

Answer:

1 2/14 ; 1 1/7

Step-by-step explanation:

To solve, change the division sign to a multiplication sign and flip the second fraction.

(4/7)/(2/4) = (4/7)(4/2)

Multiply across

(4 * 4)/(7 * 2)  = (16)/(14)

Simplify. Change to mixed fraction (& further simplify if needed).

16/14 = 1 2/14

In right triangle DEF, ∠E is a right angle, m∠D=26∘, and DF=4.5.
jok3333 [9.3K]

Answer:

The measurement of EF is 1.98 units

Step-by-step explanation:

In Δ DEF

∵ m∠E = 90°

∴ FD is the hypotenuse of the triangle

∵ m∠D = 26°

∵ EF is opposite to angle D

- We can use the sine ratio to find it

∵ sin D = \frac{EF}{FD} ⇒ (opposite side / hypotenuse)

∵ FD = 4.5 units

∴ sin(26) = \frac{EF}{4.5}

- Multiply both sides by 4.5

∴ 4.5 sin(26) = EF

∵ sin 26° ≈ 0.44

∴ 4.5(0.44) = EF

∴ 1.98 = EF

The measurement of EF is 1.98 units

Solve for g.<br> −3+5+6g=11−3g
Nataly_w [17]

Answer:

g = 1

Step-by-step explanation:

-3 + 5 + 6g = 11 - 3g

2 + 6g = 11 - 3g

Add 3g to both sides.

2 + 9g = 11

Subtract 2 from both sides

9g = 9

g = 1
