Answer:
Step-by-step explanation:
When x represents the number, "the sum of 3 and a number" is (x+3). Twice that sum is 2(x+3). "Is 30" means this expression is equal to 30:
2(x +3) = 30 . . . . an equation for the given conditions
__
We can solve this equation by dividing by 2:
x + 3 = 15
x = 12 . . . . . . subtract 3
The number is 12.
The absolute value of y is further from 0.
Explanation:
The absolute value of any number is a positive. If the value of y is greater than x, then y would be further. Let’s input a number as an example. Let’s say that the absolute value of y was 9 and the absolute value of x is 4 due to the y value being larger. 4 is closer to 0 compared to 9 so the absolute value of y is further from 0.
6.25%=0.0625
P(t) = Initial Population * (1 + rate)^t
P(t) = 400,00*(1+0.0625)^t
P(t)= 400,00*(1+0.0625)^15
Pt=400
Answer:
54
Step-by-step explanation:
We can see that the triangles are similar. We can imagine that the triangles were reflected, meaning angle ACD = angle ABD.
All of these have no solution since x would be cancelled out before it can be solved.
Hope that helps!
