22-28d = - 12 ??? geometry is hard
yarga [219]
There's not much you can or should do here other than to "solve for d."

Subtract 22 from both sides.  Then 22 - 22 - 28d = -12 - 22 = -34

Then -28d = -34, and d = -28 / (-34) = + 14/17 (answer)

kemdrick is an ecologist he spends 8 hours on friday how many hours he spending on saturday to average 11 hours per day​
Sidana [21]

Answer:

\boxed{13}

Step-by-step explanation:

        Let x = hours worked on Saturday

Then x + 8 = total hours on Friday and Saturday

\text{Average} = \dfrac{ \text{total hours}} {\text{number of days}}\\\\11 = \dfrac{x + 8}{2}

22 = x + 8

 x = 13

Kendrick is working \boxed{13} hours on Saturday.

earnstyle [38]

Answer:

The answer is 7 candies for each friend with a remainder of 3. If you are taking or have taken decimals i suggest you write 7.5 because candy can be split in half.

Step-by-step explanation:

First, multiply 4 by 10. The product is 40. Then, add 5. The sum is 45. Divide 45 by 6. The quotient is 7 with a remainder of 3.

PLEASE HELP!!! <br> BRAINLYEST!!!
11Alexandr11 [23.1K]

Answer:

C

Step-by-step explanation:

Using the rule of exponents

\frac{a^{m} }{a^{n} } = a^{(m-n)}

Note that 8 = 2³, thus

\frac{2^{5} }{8}

= \frac{2^{5} }{2^{3} }

= 2^{(5-3)}

= 2²

What is an equation of the line that passes through the point (8,-7)(8,−7) and is parallel to the line 5x+4y=165x+4y=16?
gizmo_the_mogwai [7]

Answer:

The equation of line that passes through the point (8,-7) and is parallel to the line 5x+4y=16 is  \mathbf{y=-\frac{5}{4}x+3}

Step-by-step explanation:

We need to write an equation of the line that passes through the point (8,-7) and is parallel to the line 5x+4y=16.

The equation will be of form y=mx+b where m is slope and b is y-intercept.

Finding slope of the line:

Since both the lines are parallel, and we know that parallel lines have same slope.

The slope of given line 5x+4y=16 can be found by writing in slope-intercept form y=mx+b

5x+4y=16\\4y=-5x+16\\y=-\frac{5}{4}x+16

Comparing with y=mx+b the slope m is: m=-\frac{5}{4}

So, the slope of required line is: m=-\frac{5}{4}

Now, finding y-intercept b

y-intercept can be found using slope m=-\frac{5}{4} and point (8,-7)

y=mx+b\\-7=-\frac{5}{4}(8)+b\\-7=-5(2)+b\\-7=-10+b\\b=-7+10\\b=3

So, we get y-intercept: b=3

Now, the equation of required line having slope m=-\frac{5}{4} and y-intercept b=3 is:

y=mx+b\\y=-\frac{5}{4}x+3

So, the equation of line that passes through the point (8,-7) and is parallel to the line 5x+4y=16 \mathbf{y=-\frac{5}{4}x+3}
