Answer:

Inflation can be “demand-pull” or “cost-push.” Demand-pull is “good” inflation, the kind of inflation the Fed is trying (and mostly failing) to generate. This is inflation that is caused by rising demand.

6x - 2y = 26<br><br> 2x + 3y = 5<br><br> Solve for X and Y

Softa [21]

Answer:

y is equal to -1

x is equal to 4

Step-by-step explanation:

The first thing you would do is multiply the bottom equation by a negative 3. You will get - 6x - 9y = -15. Keep the top equation the same. Both of the 6x's cancel. You then get -11y = 11 so y is equal to negative 1.

Since you have Y, you can now plug that in to any equation to find the value of x. -6x - 2(-1) = 26. You're left with 4. Plug both of the values into each equation to double check.

If the diameter of the semicircle is 1.7 centimeters, what is the circumference of the semicircle?

spin [16.1K]

The formula for circumference is $C=2 \pi r$ or $C= \pi d$ . We have a diameter for the semicircle, so let's use the diameter formula. $C= \pi (1.7)$ which is either $C=1.7 \pi$ or C = 5.338 if we multiply pi in as 3.14. BUT this is only half a circle, so we only have half that distance around the outside. Therefore, the circumference of half this circle is 2.669 cm. But we need to add the 24 mm in. 24 mm in centimeters is 2.4 cm. So 2.669 + 2.4 = 5.069
