Answer:
a = 40
t = 1
x = 6
x = 11
Step-by-step explanation:
1.
3/8 = 15/a
multiply both sides by a, then multiply by the reciprocal of 3/8
a = 8*15/3
2.
multiply both sides by 2
t = 1
3.
multiply both sides by 5
x - 3 = 30/10
x = 6
4.
multiply both sides by x - 5, then multiply by the reciprocal of 10/15
60/10 = x - 5
x = 6
Answer: C
Step-by-step explanation:
The answer would be C because you have to look at the two closest perfect squares that the number is in between. 47 is in between six squared (36) and seven squared (49). That is why the answer would be somewhere between six and seven.
Answer:
1. -1/2
2. -2/3
4. 0
5. -3/4
Step-by-step explanation:
Parallel lines have the same slope. To find the slope from the equation, use the form y=mx +b by finding m.
1. y= -1/2x - 1 has m=-1/2. This is the same slope for the parallel line.
2. y = -2/3x -1 has m = -2/3. This is the same slope for the parallel line.
4. y = 6 is a line through the y-intercept 6 on the y-axis. Because this is a horizontal line, the slope is 0. A parallel line will have 0 as the slope too.
5. 3x + 4y = 12 needs to be converted to y =mx+b.
4y = -3x +12
y= -3/4 x + 3
The slope is -3/4 so the parallel line will have the same slope.
