Answer:

Step-by-step explanation:

First multiply 5x3=15 then do 15+1=16 so then you will have 16/3 divided by 4

16/3 divided by 4= 1 1/3

if you want to can convert it you can

but the answer is 1 1/3

hope this helps if it does make sure to rate it out

and press the "thanks" button :D

2.) A zoo is raising a young elephant. They put him on a special high-protein diet to gain weight rapidly. He gains 6 kilograms

Elena L [17]

Answer:

The weight after 20 months is 210 kilos.

Step-by-step explanation:

1 month = 6 kilos
=> 8 months = 6 x 8 = 48 kilos
=> x + 48 = 138
=> x = 90

This means that the starting point is 90 kilos.

=> 1 month = 6 kilos
=> 20 months = 6 x 20 kilos
=> 20 months = 120 kilos
=> 90 + 120 = weight in 20 months
=> 210 kilos = weight in 20 months

Hence, the weight after 20 months is 210 kilos.

Hoped this helped.

Write an equation of the line containing the given point and perpendicular to the given line.

Tresset [83]

Answer:

Step-by-step explanation:

The equation of a straight line can be represented in the slope intercept form as

y = mx + c

Where

m = slope = (change in the value of y on the vertical axis) / (change in the value of x on the horizontal axis)

The equation of the given line is

9x+7y=4

7y = 4 - 9x = -9x + 4

y = -9x/7 + 4/7

Comparing with the slope intercept form, slope = -9/7

If the line passing through the given point is perpendicular to the given line, it means that its slope is the negative reciprocal of the slope of the given line.

Therefore, the slope of the line passing through (7,-4) is 7/9

To determine the intercept, we would substitute m = 7/9, x = 7 and y = - 4 into y = mx + c. It becomes

- 4 = 7/9×7 + c = 49/9 + c

c = - 4 - 49/9

c = - 85/9

The equation becomes

y = 7x/9 - 85/9

The perimeter of the triangle is 41 inches. The perimeter of the rectangle is 66 inches.

Korolek [52]

Answer:

Part A) The system of equations is equal to

$41=4x+7y$

$33=(3x+7y)$

Part B)

The length is $24\ in$

The width is $9\ in$

Step-by-step explanation:

Part A)

we know that

The perimeter of the triangle is equal to the sum of the length of its three sides

In this problem

$41=x+3x+7y$

$41=4x+7y$ -----> equation A

The perimeter of rectangle is equal to

$P=2(L+W)$

In this problem

$66=2(3x+7y)$

$33=(3x+7y)$ ------> equation B

Part B)

Using a graphing tool

Solve the system of equations

We know that

The intersection point both graphs is the solution of the system of equations

$41=4x+7y$

$33=(3x+7y)$

The intersection point is $(8,9/7)$

see the attached figure

$x=8\ in$

$y=(9/7)\ in$

step 3

Find the length and width of the rectangle

The length is 3x

$3*8=24\ in$

The width is 7y

$7*(9/7)=9\ in$
