Answer: 3x+8y=100
x+y=20
x=12
y=8
Step-by-step explanation: x would represent the number of multiple choice questions and y would represent the number of short response questions. the multiple choice questions were 3 points meaning that you need to find x. the short answer response questions were 8 points meaning you need to find y. altogether you need to get 100 points. for the second equation you have 20 questions that need to be both multiple choice and short response. therefore the second equation would be x+y=20. if you solved this, the answer would be that x equals 12 and y equals 8. hope this helped! :))
In this case u can’t use the distributive property. U just multiple whats in the parenthesis (39•5)=195 and that’s ur answer.
Let’s say if the problem said 5(2+1) u can’t use the distributive property bc u have to do what’s in the parentheses first. 5(3)=15
But If u had a problem like 2(4x+6) then u can use the distributive property. This is bc u can’t add 4x+6 bc they aren’t like terms. So u multiple the 2 by 4x which is 8x and the 2 by 6 which is 12 then ur answer would be : 8x+12
Answer:
1/35
Step-by-step explanation:
1/3 of 10 (of means multiply)
1/3 times 10 is 10/3
1/7 of 8/12=2/21
2/21 divided by 10/3
use keep change flip
2/21 divided by 10/3 equals 2/21* 3/10
1/35 is the answer
Hello,
Please, see the attached file.
Thanks.
A circle has infinit lines of symmetry. They pass through the centre of the circle and are the circle's diameter.
Hope this helps! (:
