Answer:
<h3>No solutions: 5 - 4 + 7x + 1 = 7x + 1</h3><h3>One solution: 5 - 4 + 7x + 1 = 2x + 1</h3><h3>Infinitely many solutions: 5 - 4 + 7x + 1 = 7x + 2</h3>
Step-by-step explanation:
left side: 5 - 4 + 7x + 1 = 1 + 7x + 1 = 7x + 2
<u>No solution</u> is when we have the same number of x-es and different sums of other numbers on both sides of equation. So we have to put 7 next to x and any numer except 2 at the second place.
So the right side could be 7x+1 or 7x+3 or 7x+125 and so on.
<u>One solution</u> is when we have different number of x-es on both sides of equation. The sums of other numbers could be any numbers.
So the right side could be ex.: 2x+1, x+2, 8x, 3x+(-18), and so on.
<u>Infinitely many solutions</u> is when we have the same number of x-es and the same sums of other numbers on both sides of equation. So we have to put 7 next to x and numer 2 at the second place.
So the right side has to be 7x + 2

Answer:
Yes, based on ASA or AAS
Step-by-step explanation:
Subtract the two angle values of one triangle from 180 to dictate whether the missing angle is equal to the other triangle.
180-63= 117- 45=72
The triangles are equal/congruent because two angles and a side are the same values on both triangles.
I think you subtract $110 - 5% = $105.
so, in 2014, the price was $105.
To concert a percentage into a fraction, first convert it into a decimal.
To change a percentage into a decimal, you have to take away the percentage sign and move the decimal point two places to the left.
Thus, 40% = 0.40 = 0.4
Now, to change the decimal into a fraction, you multiply both the numerator and the denominator (1) by 10.
0.4/1 = 4/10
However, in this case the fraction is in simplest form. To simplify a fraction, you have to divide the numerator and the denominator by the GCF, which in this case is 2.
4/10 = 2/5
Therefore, your answer is D. 2/5 off.
