First divide by 2, then you have
1/2x-7=-3
Then add 7 to both sides
1/2x=4
Then then divide by 1/2(which is the same as multiplying by 2)
And
x=8

When drawing the stretchout arc for the pattern of a cone fitting, the radius should be equal to _____.
garik1379 [7]

When drawing the stretch-out arc for the pattern of a cone fitting, the radius should be equal to <u>the true length of the side.</u>

The 3 tactics typically used in developing patterns are parallel-line, radial-line, and triangular improvement.

To make such objects, a drafter has to first draw them as a pattern or pattern improvement. A pattern improvement additionally known as a stretch out or simply an improvement is a format of an object made on a single flat aircraft.

In radial traces, we develop styles for shapes that have a taper, all element lines (bends) should radiate returned to a not unusual factor, a radius point. We want matters for this procedure to paintings: A radius factor is in the center (right cone). A radius point is inside an inexpensive distance.

Genevieve wants to buy a laptop that originally cost p dollars. The laptop is on sale for $100 off. Genevieve also has a 15% off
krok68 [10]

Answer:

Therefore, the resulting expression for the price Genevieve will pay

will be:  p-100-\frac{3}{20}p

Step-by-step Explanation:

Let the original cost of a laptop = p dollars

  • As the laptop on sale for $100 off
  • Genevieve also has a 15% off coupon

So, subtract the $100 and 15% off coupon (15% off on original 'p' cost)

The resulting expression for the price Genevieve will pay can be computed as:

p-100-15\%\:p

=p-100-15\frac{p}{100}

=p-100-\frac{3}{20}p        ∵ 15\%\mathrm{\:in\:fractions}:\quad \frac{3}{20}

Therefore, the resulting expression for the price Genevieve will pay

will be:  p-100-\frac{3}{20}p

Keywords: price, algebraic expression

PLS help<br> solve for x: -6(2x-5) = 18
Mashutka [201]

Hey!


-6(2x-5) = 18


Switch it around and it becomes:


2x - 5 = 18 \div -6


First find 18 ÷ -6


18 \div -6 = -3

Positive ÷ negative OR negative ÷ positive is always negative.


That leaves you with:


2x - 5 = -3


Switch that around and it becomes:


-3 + 5 = 2x


Find -3 + 5


-3 + 5 = 2


That leaves you with:


2 = 2x


Divide both sides by 2 to leave <em>x</em> alone


\frac{2}{2} =  \frac{2x}{2}


\framebox{x = 1}
