Answer:

x + (2x-12) = 84

x = 32

Step-by-step explanation:

you can say (part 1) + (part 2) = 84

one part is x (a variable) and

other part is 12 less than twice the other: when it says "12 less" is " - 12" and twice of part one 2x, you can say (2x - 12)

(part 1) + (part 2) = 84

x + (2x-12) = 84

3x - 12 = 84

3x = 96

x = 32

(part 1) + (part 2) = 84

(32) + (2*32 - 12) = 84

(32) + (52) = 84

Rick used 4 2/3 yards of fabric to sew 3 1/2 shirts. what is the unit rate of cloth he used in terms of yards per shirt
GarryVolchara [31]
For sewing 3 1/2 shirts, he used = 4 2/3 yards of fabric
Then, for 1 shirt, it would be: 4 2/3 / 3 1/2

Fabric for 1 shirt = 14/3 / 7/2
We can re-write it as: 14/3 * 2/7 = 4/3 yards

In short, Final answer would be 4/3 or 1 1/3 yards

Hope this helps!

On which of the following lines does the point (7, 1) lie?
stealth61 [152]
We have that
<span>the point (7, 1)

case </span><span>A.) y = 5x + 4
if the point </span>(7, 1) lie to the line
so
for x=7 the value of y must be  1
y=5*7+4------> y=39
39 is not 1---------> the point does not belong to the line

case <span>B.) y = -x + 8
</span>if the point (7, 1) lie to the line
so 
for x=7 the value of y must be  1
y=-7+8------> y=1--------> the point belongs to the line

case <span>C.) y = x - 10
</span>if the point (7, 1) lie to the line
so 
for x=7 the value of y must be  1
y=7-10------> y=-3
-3 is not 1---------> the point does not belong to the line

case <span>D.) y = -4x + 3
</span>if the point (7, 1) lie to the line
so 
for x=7 the value of y must be  1
y=-4*7+3------> y=-25
-25 is not 1---------> the point does not belong to the line

the answer is the option
 B.) y = -x + 8
