Answer:
Alrighty so number one is <em>5
z (x + 2y)</em>, and number two is <em>13x + 19y - 34z</em>
Answer:
5 of the 7 boxes are 8 inches in height
Step-by-step explanation:
Mathematically;
1 ft = 12 inches
So, 5 ft will measure 5 * 12 = 60 inches
So from what we have ,
We want to combine 8 and 10 inches to give 60 inches total
Let the number of 10 inches be x and the number of 8 inches be y
Mathematically;
x + y = 7 •••••(i)
10x + 8y = 60 ••••(ii)
From equation i, x = 7-y
Put this in equation ii
10(7-y) + 8y = 60
70-10y + 8y = 60
70-60 = 10y-8y
2y = 10
y = 10/2
y = 5
Hello,
Here is the formula to find the area of the trapezoid:
A=1/2(b1+b2)×h
Where b1 represent big base
b2 represent small base
and h represent height
Now, we just need to replace the number to get the final answer:
A=1/2(16.8+6.9)×2
A=1/2(23.7)×2
A=23.7 square yards. As a result, the area of the trapezoid is 23.7 square yards. Hope it help!
Find how many oz she ate: 1/2 of 3 is 1.5. 3/4 of 3 is 2.25. 1/2 of 2 is 1. Add all of the oz: 1.5+2.25+1=4.75. She ate 4.75 oz :)
36= 2*2*3*3
27= 3*3*3
10= 2*5
LCM= 2*2*3*3*3*5
LCM= 540
Final answer: 540
