Answer:
x = 4
y = 1
Step-by-step explanation:
Here, we want to solve the system of equation using elimination method
We have this as follows;
3x + y = 13
4x- 3y = 13
Multiply equation 1 by 3
9x + 3y = 39
4x-3y = 13
Add the two equations
13x = 52
x = 52/13
x = 4
From equation 1;
3x + y = 13
y = 13-3x
y = 13-3(4)
y = 13-12 = 1
Answer:
Step-by-step explanation:
Bottom triangle
Area = b * height
b = 4 + 4 = 8 cm
h = 5.75
Area = 1/2 * 5.75 * 8
Area = 23 cm^2
Trapezoid
b1 = 8
b2 = 4
h = 2
Area = (b1 + b2)*h/ 2
Area = (8 + 4)*2 /2
Area = 12
Total area = 23 + 12
Total area = 35
Step-by-step explanation:
1. 6 factors of 2 means, 2 multiplied by itself 6 times. It can be written in the form of exponents as 2⁶.
2. 
The law of exponent is : 
So,
The correct option is (A).
3. If the power of any number is 0, then the value of that number is equal to 1.
So,
Hence, this is the required solution.
Answer:
Another poorly worded homework question. While you could answer what the mean hourly snowfall was between 4PM and 7PM, that’s not what the question asks. It asks simply what the mean hourly snowfall is. You know that there are a total of 11 cm of snowfall, but you don’t know the time frame over which it fell.
So the simplest form is really an equation. 11cm / (7PM - time the snow started)
Q2. The answer is <span>D. 2w + 2 • (3w) ≤112
</span>
The perimeter of a rectangle is: P = 2w + 2l (w - weight, l - length)
<span>
The perimeter is at most 112 centimeters: P </span>≤ 112
<span>The length of a rectangle is three times its width: l = 3w
</span>P ≤ 112
2w + 2l ≤ 112
l = 3w
2w + 2 * (3w) ≤ 112
Q2.2. The answer is <span>D. 8 cm
</span>
The perimeter of a rectangle is: P = 2w + 2l (w - weight, l - length)
<span>The length of a rectangle is five times its width: l = 5w
</span><span>The perimeter is at most 96 centimeters: P </span>≤ 96
P ≤ 96
2w + 2l ≤ 96
l = 5w
2w + 2 * 5w ≤ 96
2w + 10w ≤ 96
12w ≤ 96
w ≤ 96 : 12
w ≤ 8 cm
