Answer:
Step-by-step explanation:
A. 7x + 52
Add your like terms (the numbers with variables and the numbers without)
B. 13x + 142
C. Put 8 in for x.
13(8) + 142 = 246 points
We know that C is 385, so we can plug that in to get the equation 385=15n+85. To find the number of watches, we have to solve for n.
To do that we have to...
385=15n+85
First subtract both sides of the equal sign by 85 (because we need to do the opposite)
300=15n (because 85-85 is zero, so we eliminated that, and 385-85 is 300)
Now we divide both sides of the equal sign by 15 (again, opposites)
20=n (because 15n/15 leaves us with n since both 15s cancel out, and 300/15 is 20)
So the number of watches made were 20.
Answer:
1. The greatest overall benefits appear in people who drink (2-3 )cups of coffee per day.
2. Why is it difficult to say for sure whether coffee has a good enect on the body ( lifestyle choices associated with coffee consumption also impact health).
3. Which of these is not a benefit associated with contee consumption ( lower chance of migraines.
Step-by-step explanation:
Answer:
12
Because:
30 is to 25 as x is to 10.
As an equation: 30/25 = x/10
Do this equation by: look at image
a) Rectangles always have 4 right angles (90 degrees), but parallelograms do not always have 4 right angles rather they can, but do not have to. Rectangles have to.
b) A square is a type of rectangle, but a rectangle is not a type of square. Both rectangles & squares have 4 right angles and are always quadrilaterals, but squares always have all sides that have the same length, but rectangles do not have to have their sides all equivalent lengths.
c) In the case of a parallelogram, the opposite sides are equal whereas in a rhombus all four sides are equal.
