[tex] - 0.7[/tex]

Step-by-step explanation:

[tex] \frac{1}{2} ( - 1.4m + 0.4) [/tex]

[tex] = - 0.7m + 0.2[/tex]

answer is -2/3 . Thanks a lot for giving point.

Answer:

Slope is -3

General Formulas and Concepts:

Algebra I

Slope-Intercept Form: y = mx + b

Step-by-step explanation:

Step 1: Define

Identify

y = -3x

↓ Compare to y = mx + b

Slope m = -3

y-intercept b = 0

Answer:

a) x = 11, b) x = 2/5, c) x = 1/2

Step-by-step explanation:

a)

11 x 11 x 11 = 1,331

Therefore, the answer is x = 11

b)

Reduce the fraction by the highest number 64 and 1000 go into. (which is 8)

So it'll turn into [tex]\sqrt[3]{\frac{8}{125} }[/tex]

Then reduce the fraction again, which will leave you with [tex]\frac{2}{5}[/tex]

Therefore, x= 2/5

c)

Reduce the fraction using 27.

That will give you [tex]x^{3} = \frac{1}{8}[/tex]

Then simplify the equation, which will give you [tex]x=\frac{1}{2}[/tex]

Answer:

To resolve the proposed issue, an explanation is needed in which the subject is addressed

Answer:

13 square units

Step-by-step explanation:

Look at image attached

Divide shape into two rectangles

Rectangle 1:

width: 2 units

length: 5 - 1 = 4 units

AREA: 2 x 4 = 8 sq. units

Rectangle 2:

width: 1 units

length: 5 units

AREA: 1 x 5 = 5 sq. Units

Combine area of rectangles:

8 + 5 = 13 sq. Units

That is the area of the whole polygon.

Answer:x=50

Step-by-step explanation:

28 hectares=28 0000 m2

2500

50

the area ratio is the square of the scale drawn ratio

Answer:

90.5

Step-by-step explanation:

Diagonal length of the base = √(8²+8²) = 8√2

height = 8,

so area = 8√2 × 8 (since the diagonal and the height makes the rectangle JFHL

so, 8√2 × 8

= 64√2

= 90.5

You must buy at least 30 fries to get 10 dollar ins coupons

Step-by-step explanation:

We can write a ratio to find the minimum

1 dollar            10 dollars

--------------- = -------------

3 fries                x fries

Using cross products

1 *x = 10 * 3

x = 30

You must buy at least 30 fries to get 10 dollar ins coupons

Half 37

Put into decimal

Answer:

Step-by-step explanation:

If 1/2 of the members who are present voted means, then the remaining half (1/2) didn't vote in favor of the new park.

Fraction of the members do not vote in favor of the new park = (1/2) of (37/50)

[tex]=\frac{37}{50}*\frac{1}{2}\\\\=\frac{37}{100}\\[/tex]

Triangle A and triangle B have a Similarity coefficient equal to 2 (32/16)

If 32 is the largest side therefore the other side is 16

If 32 is the smallest side so another side is 64

Answer : 16, 64

Answer:

16，64

Step-The side with a side length of 32 may be the long side or the short sideby-step explanation，so there are two cases：

1、the long side: 16/8=32/X，X=16

2、the short side：16/8=X/32，X=64
