Simplify the equation by combining like terms:

7x²+ 4x - x²

Solve:

7x²+ 4x - x²

7x² and -x² are like terms, so combine them.

6x² + 4x

There are no more like terms, so your answer would be: 6x² + 4x

Answer:

6x² + 4x

A seamstress uses 3/4 yards of material to make a uniform top for band members. If there are 6 3/4 yards of material left on the

dalvyx [7]

Answer:

She can make 9 uniform tops from the material left.

Step-by-step explanation:

Given:

Yards of material left on the bolt = $6\frac{3}{4}$

Material requirement for a uniform top for band members = $\frac{3}{4}\ yd$

To find the number of tops that can be made from the material left.

Solution:

In order to find the number of tops that can be made from $6\frac{3}{4}$ yards of material, we need to divide $6\frac{3}{4}\ yd$ by $\frac{3}{4}\ yd$ .

Number of uniform tops that can be made is given as:

⇒ $6\frac{3}{4}\div \frac{3}{4}$

We first convert mixed number to fractions.

⇒ $\frac{27}{4}\div \frac{3}{4}$

To divide fractions the fractions are multiplied after flipping the divisor.

⇒ $\frac{27}{4}\times \frac{4}{3}$

⇒ $\frac{27}{3}$

⇒ 9

Thus, she can make 9 uniform tops from the material left.

In this section, we discuss box-and-whisker plots and the five key values. The key values are called a five-number summary, which consists of the minimum, first quartile, the set is put into increasing order, divides the data into two equal parts. First, we put the values in the data set into increasing order: 3, 5, 7, 8, 12, 13, the middle score for a set of data that has been arranged in order from least to greatest. A box-and-whisker plot shows the distribution of a set of data along with... Quartiles are values that divide a set of data into four equal parts. The second Quartile ( designated Q2) also called the median or the 50th percentile (cuts data set in half ).
