You have not added your options, so I will just solve and hope that my answer is in your choices.
For the first equation we have:
3x-1=7+2
3x = 7+2+2
3x = 10
x = 10/2
For the second equation we have:
<span>2x+1+4=3
</span>2x = 3-4-1
2x = -2
x = -1
Therefore, there isn't a solution that satisfies both equations. Based on this, this system of equations has no solution.
Answer:O C
Step-by-step explanation:
X - 4 = 16
X. = 16 - 4
X. = 12
total book =1
1/5 + 2/3 + wed = 1
get a common denominator of 15
1/5 * 3/3 + 2/3 * 5/5 + wed = 1 * 15/15
3/15 + 10/15 + wed = 15/15
combine like terms
13/15 + wed = 15/15
subtract 13/15 on each side
wed = 15/15-13/15
wed = 2/15
He read 2/15 of the book on Wednesday
The area of the triangle is 90 m²
Explanation:
Given that the base of the triangle is 15 m
The altitude of the triangle is 12 m
<u>Area of the triangle:</u>
The area of the triangle can be determined using the formula,

where b is the base and h is the altitude
Thus, we have,
and 
Substituting the values in the above formula, we get,

Multiplying the terms, we get,

Dividing, we get,

Therefore, the area of the triangle is 90 m²
