Answer:
Step-by-step explanation:
This problem is all about bases and exponents. Because we have a quotient and the bases are both 5's, that means that we can use the rule of exponents for quotients to rewrite and simplify:
That's the simplification as long as you are "allowed" to leave the exponent as a negative number.
Answer:
5^-18
Step-by-step explanation:
Law of exponents bases the same add the exponents keep the base.
5^(-8+-10)=5^-18

Tonya works 60 hours in 3 weeks. Select ALL the true statements OR YOU WILL FAIL THE GRADE.
A. Tonya works 100 hours in 4 weeks.
B. Tonya works 140 hours in 7 weeks.
C. Tonya works 20 hours a week.
D. Tonya works 5 hours a day, 5 days a week.
E. At this rate, Tonya will work 240 hours in 16 weeks
Answer: b & c
Step-by-step explanation:
first i found how many hours tonya works in one week which was 20. i got that by dividing 60 by 3. then that set me up for finding the answer to the other problems as well. 60+20=80 so a wouldn’t have worked. 5x5 is 25 and she only worked 20 hours a week. and she would’ve worked 320 hours in 16 weeks, not 240. hope this helps!! :)
Answer:
B and C
Step-by-step explanation:
This problem is pretty simple if you know how to do some multiplication. First, we should figure out how many hours she works per week. You can figure this out by dividing 60 by 3. This gets us 20.
Now that we know how many hours she works each week, we can figure out the rest of the problems.
A is incorrect because 4 x 20 =80.
B is correct because 7 x 20 is 140.
C is correct because we did this problem earlier to solve the others.
D is in correct because 5 x 5 = 25, which does not equal 20.
E is incorrect because 16 x 20 = 320

Can someone help me with this
Step-by-step explanation:
Look at the top problem first.
There is only one place where you see both numbers of the ratio. It is the last column. 56/14 = 4. That means that every number on the top line has to be 4 times the number below it.
14/3.5
28/7
42/10.5
Now look at the second problem. You have 44.4 and 1332.
1332/44.4 = 30

Ten children will share a bag of candy consisting of 78 pieces. Every child will receive the same number of pieces. What is the greatest number of pieces of candy each child can receive?
(This is division and has a reminder!)
Answer:
78÷10=7.8, so roughly 7-8 pieces of candy per child.
Answer:
The max that each chiles can receive is 7 pieces. This is because when you have a remainder in this type of equation that cannot pass it out without using fractions you keep it away.

Solve the inequality.
3≤7+g
Answer:
g-4
Step-by-step explanation:
first subtract 7 from both sides
then you will get -4[tex]\leq[/tex]g
which is the same as g[tex]\geq[/tex]-4
you just have to switch them
The solution to the equation for inequality 3≤7+g is g ≥ -4. Equations and inequalities are both mathematical sentences that are formed by connecting two expressions.
How to solve the inequality ?Equations and inequalities are both mathematical sentences that are formed by connecting two expressions. The symbol = indicates that the two expressions in an equation are deemed equal. In contrast, in an inequality, the two expressions are not always equal, as indicated by the symbols: >,, or.
You test the end point by plugging it into the related equation. The inequality is then tested to see if it is correct by substituting any other solution to see if it is one of the solutions.
Rearrange the equation by subtracting what is to the right of the less equal sign from both sides of the inequality :
3-(7+g)≤0
Pull out like factors :
-4 - g = -1 • (g + 4)
Multiply both sides by (-1)
Flip the inequality sign since you are multiplying by a negative number
g+4 ≥ 0
Subtract 4 from both sides
g ≥ -4
The solution to the equation for inequality is g ≥ -4.
