Answer :
A) y = 7x + 4
Step-by-step explanation:
we need to see the equations 1 by 1
instead of y and x we need to put the value given
I am taking the last x and yes values as they are small numbers and will be easy to calculate
x = -1
y = -3
placing the values in equation :
A) y = 7x + 4
-3 = 7 × -1 + 4
-3 = -7 + 4
-3 = -3
So we got the answer same ! so the correct answer will be A) y = 7x + 4
let's check other one too to confirm overselves
b) y = 4x + 7
-3 = 4 × -1 + 7
-3 = -4 + 7
-3 = 3 NOT AN ANSWER
The guess-and-test strategy may be made easier by using the choices.
A. 38 sixth graders ----> 57 - 38 = 19 . There are 19 seventh graders. This option already satisfy the condition that the number of sixth graders should be twice that of the seventh graders. There is no need to test for the remaining choices. The answer is letter A.
Answer:
5x+3y, when x=4 and y= -3
5(4)+3(-3)=
20+ (-9)=
11

Answer:
7.34x10^22 kg can also be written as 0.0734 * 10^24 kg
Since both numbers are * 10^24, you can just add 5.97 + 0.0734 = 6.043. Then you have to add the * 10^24 giving you 6.043 * 10^24 kg
The ratio of Earth / moon is 5.97x10^24 / 7.34x10^22 = 81. The mass of the Earth is 81 times the mass of the moon.
