Answer:
A.
1.27
B.
Took what each block represented and added them together.
Step-by-step explanation:
The first block represents .89, and the second represents .38.
To add these, we just line them up and add as we usually would.
.89 + .38 = 1.27
Answer: -2, 2
Step-by-step explanation:
0 = 5x^2 -20
0 = 5(x^2 -4)
0 = 5(x - 2)(x + 2)
0 = x - 2
2 = x
0 = x + 2
-2 = x
Answer:
Associative Property
Step-by-step explanation:
Commutative: 35+(45+25) = (25+45)+35
Associative: 35+(45+25) = (35+45)+25
Distributive: cannot be done
hope this helps!
If you do 435 divided by 11, your answer would be the amount which is not a whole number, it’s 39.5454 and goes on.
but since you said NEGATIVE 435, 11 can’t go into that negative so it’ll be zero.
1. the answer is 24. think of x as the original amount, and y as the new amount. y times 1.5 is x, and y+12 is x. reverse that to figure out y, which is what we need, and you have x/1.5 = y as well as x-12 = y. Use the equal values method and make an equation x/1.5=x-12. solve this equation to get x, which is 36. to figure out the new amount, y, you need to subtract 12, which would help you get 24 as your final answer.
2. once again, create an equation. let's call team 1 x and team 2 y. team one has 1/4th as many as team 2, so that would be x=1/4y. An easier way to write that is 4x=y. after 6 people quit team two, that would be y-6. after the transfer, that would be y-6-12, and x+12 for the teams. they are equal after these, so y-6-12=x+12. solve this equation to get y-18= x+12. if you recall earlier, y was 4 times x, so substitute that into y to get 4x-18=x+12. Solve the equation to get 10 people on team one originally. your final answer is 10 people.
