Define a variable write an equation and solve the problem. the width of a rectangle is 3 meters more than one-fourth its length.

sweet [91]

Let's assume

length of rectangle is L

width of rectangle is W

the width of a rectangle is 3 meters more than one-fourth its length

so,

$W=3+\frac{1}{4} L$

the perimeter is 10 meters more than twice its length

we know that

perimeter =2(L+W)

so, we get

$2(L+W)=10+2L$

now, we can simplify it

$2L+2W=10+2L$

subtract both sides by 2L

$2L+2W-2L=10+2L-2L$

$2W=10$

$W=5$

now, we can find L

$5=3+\frac{1}{4} L$

subtract both sides 3

$5-3=3-3+\frac{1}{4} L$

$2=\frac{1}{4} L$

multiply both sides by 4

$4*2=4*\frac{1}{4} L$

$L=8$

so,

length of rectangle is 8 meter

width of rectangle is 5 meter ............Answer

In a classroom of 33 students, the ratio of boys to girls is 3:8. How many boys are in the class?

Hunter-Best [27]

X=number of boys
y=number of girls.

We can suggest the following system of equations:
x+y=33
x/y=3/8

We solve this system of equations by substitution method.
x/y=3/8 ⇒x=3y/8

(3y/8)+y=33
least common multiple=8
3y+8y=33*8
11y=33*8
y=(33*8)/11
y=3*8
y=24

x+y=33
x+24=33
x=33-24
x=9

number of boys /total number of students=9/33=3/11

There are 9 boys and 24 girls in the class.

Answer: C: 9. since 3/11 of the students are boys.

Wyatt is making a salad using tomatoes, cucumbers, and carrots. This table gives the cost, per kilogram, of each ingredient, and

Lina20 [59]

According to the given information, we build the equation for the cost. After we build the equation, the equation that relates these measures is:

$C = 0.99 + xy + 0.2z$

Cost:

0.3 kilograms of tomatoes, at 3.30 dollars per kilogram.

Thus, the cost starts at:

$C = 0.3*3.3 = 0.99$

y kilograms of cucumbers, at x dollars per kilogram.

Considering this, the cost will now be of:

$C = 0.99 + xy$

0.2 kilograms of carrots, at z dollars per kilogram:

Now, we have to consider this for the cost, so:

$C = 0.99 + xy + 0.2z$
