Answer

y=35-15x

Step by step

Subtract 3x from both sides

1/5y=7-3x

Divide by 1/5 (times by the reciprocal wich is 5)

y=35-15x

Answer:

x = 35 - y / 15

Step-by-step explanation:

3x + 1/5y = 7

3x + 1/5y - 1/5y = 7 - 1/5y

3x = 7 - 1/5y

3x/3 = 7/3 - 1/5y / 3

x = 35 - y / 15

Ricky rides his bike 12 miles every day he stops 7 miles to rest write and solve an equation to find out how much further he has
kondor19780726 [428]
<h3><u>Question:</u></h3>

Ricky rides his bike 12 miles every day. He stops after 7 miles to rest. write and solve an equation to find out how much further he has to ride

<h3><u>Answer:</u></h3>

Ricky has to further ride for 5 miles

<h3><u>Solution:</u></h3>

Given that, Ricky rides his bike 12 miles every day

Let "x" be the remaining distance in miles he has to ride further

Total distance = 12 miles

Also, given that he stops after 7 miles to rest

Therefore, already covered distance = 7 miles

Therefore, we can frame a equation as,

remaining distance + already covered distance = total distance

x + 7 = 12

Solve the above equation for "x"

x = 12 - 7

x = 5

Thus Ricky has to further ride for 5 miles

There is enough information to prove that triangles tno and gcm are congruent. true false
Hatshy [7]

False,  there is not enough information provided to Prove that both the triangles are congruent.

<h3>What is the congruent triangle?</h3>

Triangles have three sides and three angles, as we discovered in pre-algebra. We also discovered that a triangle's total angle is 180 degrees.

Congruent triangles are two triangles that are the same size and shape. Two congruent triangles remain congruent even if we flip, turn, or rotate one of them.

Two triangles must have the same angles and, as a result, must be congruent if their sides are the same. If two triangles are congruent or not, we may determine this simply by looking at their sides.

These two triangles are also equivalent if we know that two sides of one triangle and the angle between them are congruent to two sides and the angle between them of another triangle.

If we know that two angles and the side between them in one triangle are congruent with two angles and the side between them in another triangle, then these two triangles are probably congruent.

When two angles and a non-included side in one triangle are congruent to the corresponding angles and side of another triangle, we are left with the final scenario that results in congruent triangles.

The given data doesn't satisfy any of the conditions.

Hence, there is not enough information provided to Prove that the two triangles are congruent.
