Write the sum of -5x - 7y + 6 and -4 + 3x in standard form.

Mathematics

Answer:

Step-by-step explanation:

first, you need to know what standard form is

Ax + By = C

which is basically

number(x) + number(y) = number

to put it simply..

so now we can evaluate the expression (the random mess they gave us)

-5x - 7y + 6 and -4 + 3x

we need to put em together so just toss an equal sign between em

so now we have

-5x - 7y + 6 = -4 + 3x

no combine like terms

-8x - 7y + 6 = -4

-8x - 7y = -10

and thats the answer in standard form

heyy soo i just started math class and im veryy confused I've tried different things to get to the answer but it didn't work soo
german

yes sure, i learned this before so

1. a. make a proportion here, of percentage. \frac{225}{250} =\frac{x}{100} if you cross multiply and divide you get 90%.

1. b. obviously the empty seats would be 10%.

2. a. proportion again, \frac{0.90}{6.00} =\frac{x}{100} cross multiply then divide you ge 15%

3. 30% in decimal form is 0.3. multiply it then to the total amount, so 0.3 x 15 = 4.5

Save Work out the size of angle AED.<br> b) Work out x
Mamont248 [21]

Answer:

x = 10°

Step-by-step explanation:

a). Since, opposite angles of a cyclic quadrilateral are supplementary angles"

   Therefore, in cyclic quadrilateral ABDE,

   m∠ABD + m∠AED = 180°

   110° + m∠AED = 180°

   m∠AED = 180° - 110°

                 = 70°

b). AD = ED [Given]

   m∠EAD = m∠AED [Since, opposite angles of equal sides are equal in measure]

   m∠EAD = m∠AED = 70°

   By triangle sum theorem in ΔABD,

   m∠BAD + m∠ABD + m∠ADB = 180°

   m∠BAD + 110° + 40° = 180°

   m∠BAD = 180 - 150

                 = 30°

    m∠AEB = m∠AED + m∠DAB [By angles addition postulate]

    m∠AEB = 70° + 30°          

                  = 100°

    By triangle sum theorem in the large triangle,

    x° + m∠AEB + m∠EAB = 180°

    x° + 100° + 70° = 180°

    x = 180 - 170

    x = 10°

A block in the shape of a cube has sides that are 2 over 1\2 inches long. what is the volume of the block????
Vlad1618 [11]
A cube has equal sides if they are 2÷ 1/2 each then L×W×H would be (2÷ 1/2)^3. To divide fractions we multiply the reciprocal.

2÷ 1/2 = 2/1 × 2/1 = 4

4×4 = 16×4= 64

answer is V = 64 inches cubed.

Feliz [49]

Answer:

1

Step-by-step explanation:

Distance between x's (Δx)

0

This field is calculated automatically, you cannot change it's value manually.

Distance between y's (Δy)

1

d = √(Δy2 + Δx2) = √(12 + 02) = √1 = 1
