Perform the multiplication first, following Order of Operations Rules:
<span>26u+4(12u-5)=128 => 26u + 48u - 20 = 128
Then 74u = 148, so u = 2. This is the "solution," the value of u that makes </span><span>26u+4(12u-5)=128 true.</span>
Answer:
480 ft
Step-by-step explanation:
To find the width (x), apply the similarity theorem of two similar triangles, which says that the corresponding lengths of two similar triangles are proportional.
Thus:
x/72 = 80/12
Cross multiply
12 × x = 80 × 72
12x = 5,760
12x/12 = 5,760/12
x = 480
Width of the canyon = x = 480 ft
Answer:
6 work out sessions
Step-by-step explanation:
From the above question, we know that:
Jasmine has a goal to workout a total of at least 6 hours this week.
Her workout sessions are always 3/4 an hour long.
Hence: Her total workout sessions
3/4 hour = 1 workout session
6 hours = x
Cross Multiply
3/4 × x = 6 × 1
x = 6/3/4
x = 6 ÷ 3/4
x = 6 × 4/3
x = 8 work out sessions
We are told that:
She already worked out for 1 1/2 hours.
Hence: if :
3/4 hour = 1 workout session
1 1/2 hours = x
Cross Multiply
3/4 × x = 1 1/2
x = 1 1/2 ÷ 3/4
x = 3/2 ÷ 3/4
x = 3/2 × 4/3
x = 2 work out sessions
Therefore:
the minimum number of workout sessions she would need to complete in order to achieve her weekly goal is calculated as:
8 work out sessions - 2 work out sessions
= 6 work out sessions
Converting this to workout sessions
The answer for the first quartile would be 51.5
3400. Should be the answer. I’m sorry if it is incorrect
