2 2/3 + 2/3 + 1/4 =
8/3 + 2/3 + 1/4 =
10/3 + 1/4 =
40/12 + 3/12 =

Answer:

$9C=5(F-32)$

Step-by-step explanation:

The equation which can convert the temperature from degree Celsius into degree Fahrenheit is given as under

$9C=5(F-32)$

We can solve it further for F as

$9C=5F-5 \times 32$

$9C=5F-160$

$9C+160=5F$

Dividing both sides by 5 we get

$\frac{9C}{5}+32=F$

$F=\frac{9C}{5}+32$

Now substituting values of C in this equation will give us the corresponding values of F

Ex : C=1

$F=\frac{ 9\times 1}{5}+32$

$F=\frac{ 9+160}{5}$

$F=\frac{ 169}{5}$

Hence 1 degree Celsius is $\frac{ 169}{5}$ degree Fahrenheit

Find and equation for the line that passes through the points (-6,-4) and (4,4).

Ghella [55]

We have (x-4)/(-6-4) = (y-4)/(-4-4);
(x-4)/(-10) = (y-4)/(-8);
(x-4)/5 = (y-4)/4;
4x-16 = 5y-20;
4x - 5y + 4 = 0;

An angle measures 148° more than the measure of its supplementary angle. What is the measure of each angle? AND DONT PLAGERISE!!

Usimov [2.4K]

Answer:

Step-by-step explanation:

Supplementary angles add up to 180°.

“θ is 148° more than its supplement”

Supplement of θ = 180°-θ

θ = (180°-θ) + 148°

2θ = 328°

θ = 164°

Supplement of θ = 180°-164° = 16°

Please hellllllllppppppppppppppppppppppppppp

vitfil [10]

Answer:

$21^{10}$

Step-by-step explanation:

First, multiply the 3 and the 7 together, and then "multiply" the exponents -8 and 3. (However, when "multiplying exponents, you're really just adding them together: -8 + 5)

( $21^{-5}$ )^2

Then, multiply the -5 and -2 together, giving you:

$21^{10}$
