Aboslute value|10 blocks| + |3 blocks| + |-8 blocks| + |2 blocks| + |-7 blocks| + |4 blocks| + |-4 blocks| = ?

1 answer:

5 0

Absolute or modulus always gives a positive number.
For example, when I take absolute value of 4, I get
|4| = 4 and when I take absolute value of -4, I get |-4| = -(-4) = 4.

Therefore, no matter what the sign of quantity is, absolute or modulus will always make it positive.
Therefore,
|10 blocks| + |3 blocks| + |-8 blocks| + |2 blocks| + |-7 blocks| + |4 blocks| + |-4 blocks| = 10 + 3 -(-8) + 2 -(-7) + 4 -(-4) = 10+3+8+2+7+4+4 = 38

What is the solution to the system? x + y = 4 x+y=1

Lelechka [254]

Given :

x + y = 4
x + y = 1

To Find :

The value of x and y.

Answer :

x + y = 4 ....[Equation (i)]
x + y = 1......[Equation (ii)]

Adding eqⁿ (ii) and eqⁿ (i) we get :

→ x + y + x - y = 4 + 1

→ 2x = 5

→ x = 5/2

→ x = 2.5

Now, put the value of x = 5/2 in eqⁿ (i) we get :

→ x + y = 4

→ 5/2 + y = 4

→ y = 4 - 5/2

→ y = 1.5

5. Lauren is saving for gymnastics camp, Camp costs $225 to attend. She has 40 percent of the money saved. How much money has sh

barxatty [35]

To solve this problem you have to convert the percentage to a decimal which would
be .40.

40% =40/100=.40

After doing so all you need to do is divide the amount needed by the percentage which gives you the amount she has saved.

225/.40= $90

Lauren has $90 saved

Type the correct answer in the box. Jason builds doghouses for a pet store. Each doghouse is a wooden structure with a rectangul

Basile [38]

Answer:

Width = 3 feet

Length = 7 feet

Step-by-step explanation:

x represents the width of doghouse so,

Width = x

Length is 4 times more than its width

Length = x+4

Area of doghouse = 21 square feet

We know

Area of rectangle = Length * Width

21 = (x+4)*x

21 = x^2+4x

=> x^2+4x-21=0

Solving the above quadratic equation by factorization to find the value of x

x^2+7x-3x-21=0

x(x+7)-3(x+7)=0

(x+7)(x-3)=0

x+7 =0 and x-3=0

x= -7 and x =3

Since the width of rectangle can never be negative so, x=3

Width =x = 3 feet

Length = x+4 = 3+4 = 7 feet
