Find 50% of 180 pls explain
Doss [256]

Answer:

50% of 180 is 90

Step-by-step explanation:

50% is like saying half. They want you to find half of 180, if you know 9 times 2 equals 18, then you already know the answer, all you have to do is add a 0 on the end of the 9.

Or if you're not as strong with mental math, plug into a calculator 180 times the decimal version of 50% which is .5. 180 times .5 equals 90.

In bulk, jelly beans cost 18 cents per ounce. What is the cost of the jelly beans in dollars per pound?
Diano4ka-milaya [45]

So we know that there are 16 ounces in one pound, so let's multiply to find how many cents one pound of jelly beans cost:

16*8=128cents

And we know that there are 100 cents in one dollar, so let's divide this by 100:

\frac{128}{100}=1.28

So the jelly beans cost $1.28 per pound.

What is the value of a in the equation 5a -10b = 45 when b = 3
leva [86]
Salutations!

5a-10b = 45

value of b = 3

Multiply 10 and 3

10*3=30

Now, you can solve the equation --

5a-30=45

separate the variables aside, and the numbers aside.

5a=45 +30

5a=75

a=75/5

a=15

Hope I helped (:

Have a great day!

Nathaniel is using the quadratic formula to solve 0 = x2 + 5x - 6. His steps are shown below. What are the solutions to the equa
Elena L [17]
The quadratic equation is;
x²+5x-6 = 0
x²+6x-x-6 = 0
x(x+6)-1(x+6) = 0
(x+6)(x-1) = 0
So,
x+6 = 0 and x-1 = 0
x=-6 and x = 1
Thus the answer is
x = -6,1
