Yes, because 23 hundreds is 23,000 and 7 tens is 70 and 5 ones is 5
Just look at the percentages and make them into fractions. You can think about it like money. 50 cents is half of a dollar, so %50 is 1/2. for the decimals, you just take the percent and put a decimal point in front of the answer, so 28% is .28, 50% is .50, 18% is .18. For fraction to decimals, you could just put 1 divided by 4 into a calculator and it will tell you .25, which is the decimal, and 25 cents is one fourth of a dollar, so it works out.
Hope this helps! Let me know if you have any more questions!
SYSTEMS OF EQUATIONS. A system of equations is a collection of two or more equations with a same set of unknowns. In solving a system of equations, we try to find values for each of the unknowns that will satisfy every equation in the system.
I'll solve problem 3 (I think it's what you're asking)
All the ones you answered on problem 3 are correct.
I'll solve the rest
c) KM = 26
The diagonals of a rectangle are congruent.
If the measure of one diagonal is 26 (which is 13 + 13), the other one is 26.
d) m∠KLM = 90
It's a rectangle! It's supposed to have 4 corners with right angles.
∠KLM is a corner of the rectangle
f) m∠LJM = 22
Subtract 68 from 90 since you know ∠LJK = 68
90 - 68 = 22
Question 1, 2, and 4 is a bit hard to see.
Have an awesome day! :)
