5−4+7+1= 5 - 4 + 7 x + 1 = how is it no solution

laila [671]

Answer:

There is a solution. Here's how:

Step-by-step explanation:

So, you work out the problem, and you lay it out here:

5-4+7+1=5-4+7x+1.

First, you start by subtracting 5 from both sides, which cancels both of the 5s. Here's your equation now:

-4+7+1=-4+7x+1

Next, you add 4 to both sides, which makes you identify the identity.

Here's your equation now:

7+1=7x+1

Now, you subtract 1 from both sides.

Here's your equation now:

7=7x

Finally, divide both sides by 7, while identifying the identity.

x=1.

How do I use the arc length to find the circumference ?

Mashutka [201]

arc length = circumference • [central angle (degrees) ÷ 360]

Solving this equation for circumference:

circumference = arc length / (central angle / 360)

circumference = 12 / (85/360)

circumference = 12 / 0.2361111111 

circumference = 50.8235294118

Cora makes a scarf with cloth rectangles and triangles. For every 5 pieces of cloth, 2 are rectangles. She needs 15 pieces of cl

PtichkaEL [24]

Answer: There are 6 pieces of cloth are rectangles and 9 pieces of cloth are triangles.

Explanation:

Since we have given that

For every 5 pieces of cloth, 2 are rectangles

So, remaining piece will be of triangle so,

$5-2=3$

3 are triangles.

Ratio of rectangles to triangles is 2:3.

Now, she needs 15 pieces of cloth to complete her scarf,

So, Number of rectangles is needed is given by

$\frac{2}{5}\times 15\\\\=2\times 3\\\\=6$

Number of triangles is needed is given by

$\frac{3}{5}\times 15\\\\=3\times 3\\\\=9$

Hence, there are 6 pieces of cloth are rectangles and 9 pieces of cloth are triangles.
