Consider this solution to a problem.

Mathematics
1 answer:
Aleonysh [2.5K]3 years ago
4 0

Answer:

1. The mistake was the sign that was put negative instead of positive.

2. y = 4

Step-by-step explanation:

​In the first response box, enter the number of the step where the mistake is made.

​Step:

The mistake is on step 1: This is the distributive property, however it was distrubuted wrong since the signs were used wrong.

-4(6-y)+4=-4 does not equal  -24-4y+4=-4

The reason is because -4 x -y is not equal to -4y because negative x negative = positive. So, it's equal to +4y.

In the second response box, enter the correct solution to the problem.​

Problem: -4(6-y)+4=-4

Step 1: -24 + 4y + 4 = -4 (Distributive Property Of Equality)

Step 2: -20 + 4y = -4 (Combine Like Terms)

Step 3: 4y = 16 (Addition Property Of Equality)

Step 4: y = 4 (Division Property Of Equality)

Ben also participated. He fell down midway, and had to walk part of the distance. Still, he finished the distance! It took him e
Fynjy0 [20]

Answer:

0.56 m/s

Step-by-step explanation:

The average speed of a body tells how fast is the body moving; it is calculated as:

v=\frac{d}{t}v=td

where

d is the distance covered

t is the time elapsed

In this problem, we don't know the distance covered by Ben. Therefore, we will assume that it is 1 km:

d = 1 km = 1000 m

The time elapsed to cover this distance is:

t=30 min \cdot 60 =1800 st=30min⋅60=1800s

Therefore, Ben's average speed is:

v=\frac{1000}{1800}=0.56 m/sv=18001000=0.56m/s

Hope this helps

-5x + y = -2, -3x + 6y= -12. Solve each system by substitution
Ahat [919]

Answer: x = 0, and y = -2

Step-by-step explanation:

-5x + y = -2 .........(1)

-3x + 6y = -12 ......(2)

From equation (1)

-5x +y = -2 .........(1)

y = 5x - 2 .............(3)

Now substitute for y  in equation (2)

-3x + 6 (5x -2 ) = -12

Make use of 6 to open the bracket ,we now have

-3x + 30x - 12 = -12

= 27x - 12 = -12

Collect the like terms

27x = -12 + 12

27x = 0

Divide through by 27 to get the value of x

x = 0/27

x = 0

To determine y, substitute for x in equation (3)

y = 5x - 2

y = 5(0) - 2

y = 0 - 2

y = -2

Check : Substitute for x and y in equation (1)

-5x + y = -2

-5(0) + (-2) = -2

0 -2 = -2

0 - 2 = -2

Lexi needs 144 beads.A large box holds 100 beads.A medium box holds 10 beads.a small box holds 1 bead.lexi already had 1 large b
saveliy_v [14]

The total number of beads that Lexi could accommodate based on the on hand items is 101 beads. Subtract the number of beads she needs which is 144 beads with 101 beads. The amount of beads that would need a box is 43 beads. Since a medium box could only accommodate 10 beads at a time, divide 43 with 10 and the answer would be 4 remainder 3. Thus Lexi would only need 4 medium boxes.
