Answer:
70 + 95 = 5(14 + 19)
Step-by-step explanation:
70 + 95 = 5(14 + 19)
gcf = 5
14x + 7y = 217 > lets solve for y first > so 14(0) + 7y = 217 > 7y = 217 > y = 7/217 > y = 31 > 14x + 7(0) = 217 > 14x = 217 > x = 14/217 > x = 15.5
Now but the 31 in the y place and the 15.5 in the x place and see if it matches up with 217
Answer:
f(x)=x+2.
f(1/3x)=1/3 x+2=(x+6)/3or x/3+2
Answer:
50 & 105
Step-by-step explanation:
We need to find the 2 numbers >>>>
Let first number be a
and second number be b
Also, let a < b
Now, "twice a number PLUS twice another number is 310". Thus, we can write an equation as:
2a + 2b = 310
The difference (larger minus smaller) is 55, so we can write:
b - a = 55
also can be written as b = 55 + a
Now we replace 1st equation with 2nd equation and write an equation in "a" and solve for a first:
We know,
b = 55 + a
so
b = 55 + 50
b = 105
So the two numbers are 50 & 105
