neonofarm [45]3 years ago
6 0

Step-by-step explanation:

\frac{3}{4} x +  \frac{7}{8}  = 4 \frac{1}{4}

\frac{3}{4} x =  \frac{17}{4}  -  \frac{7}{8}

\frac{3}{4} x =  \frac{34}{8}  -  \frac{7}{8}

\frac{3}{4} x =  \frac{27}{8}

3x \times 8 = 27 \times 4

24x = 108

x =  \frac{108}{24}

x =  \frac{9}{2}

Is the point (3, -2) a solution to the following system of equations? How do you know?
iris [78.8K]

Answer:

YES

Step-by-step explanation:

Any straight line can be represented by an equation of the form

Y = mX + b

where m is the slope and b is the Y intercept, so these two equations are lines. The only solution is where the two lines cross, so must satisfy both equations. Plugging in 3 for X and -2 for Y we get

Y = -3X + 7

-2 = -3(3) + 7

-2 = -9 + 7

-2 = -2 True

AND,

Y = 2X - 8

-2 = 2(3) - 8

-2 = 6 - 8

-2 = -2 True

So since both are true, yes (3, -2)  is the solution.

Tell whether the angels are complementary or supplementary then find x
NNADVOKAT [17]

Answer:

Supplementary angles

x = 31

Step-by-step explanation:

Since, (3x + 25)° and 2x° are straight line angles. Therefore they are supplementary angles

(3x + 25)° + 2x° =180°

(5x + 25)° = 180°

5x + 25 = 180

5x = 180 - 25

5x = 155

x = 155/5

x = 31
