Let x = the first number
Let y = the second number
So we can set up two equations:
x+y = 400
.8x + .85y = 400-68
Use substitution:
y = 400 - x
.8x + (.85)*(400-x) = 332
.8x + 340 -.85x = 332
8 = .05x
x = 160
So that makes y = 240
We want the decreased values so:
160*.8 = 128
240*.85 = 204
So the answers are 128 and 204
Number of possible outcome = (17 x 16 x 15) ÷ (1 x 2 x 3) = 680
Answer: 680.
Length = 4x
width = 7x
perimeter is 2length+2width= 352
2(4x)+2(7x) = 352
8x+14x =352
22x = 352
x = 16
then length = 4*16=64
width =7*16=112
Answer: 270 cubic centimeters
Step-by-step explanation:
bh/3 is the formula so...
because it's a right triangle we multiply the legs together:
9*12 = 108
and we divide by 2
108/2 = 54
height is 15
(15*54)/3 = 810/3 = 270
Our answer is 270 cubic centimeters.
<h3>
Answer:</h3>
The value of k is 7
<h3>
Step-by-step explanation:</h3>
<em>1. We know f of x is going to be are starting line because it is listed in the equation first.</em>
<em>2. Both f of x and g of x have y intercepts</em>
<em>3. From f of x, count up until you reach g</em>
<em>4. The answer is 7, since you vertically shifted up 7 units</em>
