Saira weights 25 pounds more than umbar . If together they weight 205 pounds. What is the weight of saira

1 answer:

6 0

To solve this, you can create an equation. Say the weight of Umbar is x, then Saira weighs x+25. Together they weigh 205. So, you get the equation

x+x+25=205

Then solve for x.

2x+25=205
2x=180
x=90

Then to find Saira's weight, add 25 to Umbar's weight.

90+25=115.

Mrs Leon bought 6 rolls of toilet paper and 5 bottles of hand sanitizer for $32. Ms Ramirez bought 4 rolls of toilet paper and 1

zlopas [31]

Answer:

The cost of a roll of toilet paper is $2 and the cost of a bottle of hand sanitizer is $4.

Step-by-step explanation:

Given:

Mrs Leon bought 6 rolls of toilet paper and 5 bottles of hand sanitizer for $32.

Ms Ramirez bought 4 rolls of toilet paper and 1 bottle of hand sanitizer for $12.

Now, to find the cost for each item sold.

Let the cost of a roll of toilet paper be $x.$

And the cost of a bottle of hand sanitizer be $y.$

So, the cost of 4 rolls of toilet paper and 1 bottle of hand sanitizer:

$4x+y=12\\\\y=12-4x\ \ \ \ .....(1)$

Now, the cost of 6 rolls of toilet paper and 5 bottles of hand sanitizer:

$6x+5y=32$

Substituting the value of $y$ from equation (1):

$6x+5(12-4x)=32$

$6x+60-20x=32$

$60-14x=32$

Subtracting both sides by 60 we get:

$-14x=-28$

Dividing both sides by -14 we get:

$x=2.$

The cost of a roll of toilet paper = $2.

Now, substituting the value of $x$ in equation (1):

$y=12-4x\\\\y=12-4\times 2\\\\y=12-8\\\\y=4.$

The cost of a bottle of hand sanitizer = $4.

Therefore, the cost of a roll of toilet paper is $2 and the cost of a bottle of hand sanitizer is $4.

What is the equation of the

kati45 [8]

Answer:

y = $\frac{1}{3}$ x + 4

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 3x + 6 ← is in slope- intercept form

with slope m = - 3

given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{-3}$ = $\frac{1}{3}$ , then

y = $\frac{1}{3}$ x + c ← is the partial equation of the perpendicular line

to find c substitute (3, 5 ) into the partial equation

5 = 1 + c ⇒ c = 5 - 1 = 4

y = $\frac{1}{3}$ x + 4 ← equation of perpendicular line

Answer:

a) 0

b) 4.5

c) 3

d) 6

Step-by-step explanation:

Formula: 3x + 4y = 12

The questions contains the values of x. So here's an example of:

d) x = -4, y = ?

Using the formula: 3(-4) + 4y = 12

-12 + 4y = 12

4y = 24

y = 6

Do the same for the others!

If the spinner is spun, what is the probability that the spinner will land on a multiple of 4

vesna_86 [32]

In the usual spinner that we have, the circular figure is divided into 8 equal parts. Each of which is numbered from 1 to 8. There are two of these numbers that are multiple of 4 (4 and 8). Now, the probability that the spinner will land on a multiple of 4 is equal to 2/8 or also equal to 1/4 or 0.25.
