First find the sum:
31 +60=91
92×91=(90×90)+(90×1)+(2×90)+(2×1)
8100 + 90.+ 180 + 2=
8372.

What is the equation of the line will mark you brainliest

Delvig [45]

so you're going to need to find the slope. in order to do that use (y2-y1)/(x2-x1)

(7-(-2))/(0-8)

simplify

9/-8

simplify -9/8

now using y=mx+b, we need to find b. so we can plug in the coordinates of (0,7) or (8,-2). let's use (8,-2) because it involves more math.

y=mx+b

-2=(-9/8)(8)+b

multiply (-9/8) by 8 to get -9

-2=-9+b

add 9 to both sides

7=b

so our equation is now

y=-(9/8)x+7

(3x-4)/(14)=(9)/(10) Solve the proportion. Round to the tenths

____ [38]

The value of "x" is 5.5

<em><u>Solution:</u></em>

Given that we have to solve the proportion

$\frac{3x - 4}{14} = \frac{9}{10}$

We can solve the above given proportion for "x" by cross multiplying

Multiply the numerator of the left-hand fraction by the denominator of the right-hand fraction

Multiply the numerator of the right-hand fraction by the denominator of the left-hand fraction

Set the two products equal to each other

Solve for the variable "x"

$\rightarrow \frac{3x - 4}{14} = \frac{9}{10}\\\\\rightarrow 10(3x - 4) = 14 \times 9\\\\\rightarrow 30x - 40 = 126\\\\\rightarrow 30x = 126 + 40\\\\\rightarrow 30x = 166\\\\\rightarrow x = 5.533$

On rounding to nearest tenth we get 5.5

Thus value of "x" is 5.5
