−5(−x−1)+4x−1= 49 solve for x

Answers

Answer:

x = 5

Step-by-step explanation:

Solve for x:

-1 - 5 (-x - 1) + 4 x = 49

-5 (-x - 1) = 5 x + 5:

(5 x + 5) + 4 x - 1 = 49

Grouping like terms, 5 x + 4 x - 1 + 5 = (5 x + 4 x) + (-1 + 5):

((5 x + 4 x) + (-1 + 5)) = 49

5 x + 4 x = 9 x:

9 x + (-1 + 5) = 49

5 - 1 = 4:

9 x + 4 = 49

Subtract 4 from both sides:

9 x + (4 - 4) = 49 - 4

4 - 4 = 0:

9 x = 49 - 4

49 - 4 = 45:

9 x = 45

Divide both sides of 9 x = 45 by 9:

(9 x)/9 = 45/9

9/9 = 1:

x = 45/9

The gcd of 45 and 9 is 9, so 45/9 = (9×5)/(9×1) = 9/9×5 = 5:

The product of a number, x, and seven is two less than 5 times the difference of the same number, x, and three


Please help

Answers

Answer: -8.5 or -17/2

Step-by-step explanation: you have to put the info into an equation. product of a number x and 7 is 7x. two less than mean subtracting two and 5 times the difference of x and 3 translates to 5(x-3). Once put into an equation, it'll look like 7x = 5(x-3) - 2. Now solve this equation for x and you'll end up with -8.5 in decimals or -17/2 in fractions.

Answers

Answer:

18

Step-by-step explanation:

116-98

so sorry if its incorrect

Answer:

34 degrees

Step-by-step explanation:

ahahah okay this is fun

so what you should do here is extend the line that passes through the 116 and 98 degree angle so that it passes the other parallel line.

It makes a triangle doesn't it

One of the angles is supplementary to 98, so 180-98 = 82 degrees.

Another one of the angles is the opposite angle to the supplementary angle of 116 (remember your line-intersecting-parallel-lines angles), therefore 180-116 = 64 degrees

The last angle of that triangle is the opposite to angle 4, and you can find that using the other two angles of the triangle we made earlier, which you get 180-82-64 = 34 degrees

a line, y=mx+b, passes through the point (1, 6) and is parallel to y=4x+6. What is the value of B?

Answers

Answer:

B = 2

Step-by-step explanation:

I used Desmos to get a visual representation to help.

The equation y = 4x + 6 has a y - intercept at (6,0).

The equation y = 4x + 2 has a y - intercept at (2,0) and passes through (1,6).

Hope this helps!

The value of  B = 2 when a line, y=mx+b, passes through the point (1, 6) and is parallel to y=4x+6.

What is an equation?

The equation in mathematics is the relationship between the variables and the number and establishes the relationship between the two or more variables.

The equation y = 4x + 6 has a y - intercept at (6,0).

The equation y = 4x + 2 has a y - intercept at (2,0) and passes through (1,6).

Therefore the value of  B = 2 when a line, y=mx+b, passes through the point (1, 6) and is parallel to y=4x+6.

Answers

Answer:

[tex]\sqrt{29}[/tex]

Step-by-step explanation:

You would use the Pythagorean Theorem: [tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]

The a and b is the legs and the c is the hypotenuse

So when you fill it in you get [tex]2^{2}[/tex] + [tex]5^{2}[/tex] = [tex]c^{2}[/tex]

continue to solve the equation 4+25= [tex]c^{2}[/tex]

29 = [tex]c^{2}[/tex]

then you would square root it

c = [tex]\sqrt{29}[/tex]

Step-by-step explanation:

-4m + 5 + 2m = 3 - 4m

Add up light terms

-2m + 5 = 3 - 4m

Subtract 3 from both sides.

-2m + 2 = -4m

Add 2 to both sides.

Bags of flour come in 3 sizes: Small bag: A 200 g bag costs 40p. Medium bag: A 1 kg bag costs £1.80. Large bag: A 2 kg bag costs £3.80. Calculate the cost of 1 kg for the small and large bags. Give your answer in pounds to 2 dp.

Answers

Answer:

Small bag: 1kg cost 200.00p

Large bag: 1kg cost £1.90

Step-by-step explanation:

Small bag: A 200 g bag costs 40p

Medium bag: A 1 kg bag costs £1.80.

Large bag: A 2 kg bag costs £3.80.

Calculate the cost of 1 kg for the small and large bags.

Small bag: A 200 g bag costs 40p

200g cost 40p

1 gram cost 40/200

1 gram = 0.2 p

1000 g = 1kg

1kg cost = 0.2p × 1000

= 200.00p

Small bag: 1kg cost 200.00p

Large bag: A 2 kg bag costs £3.80.

Cost of 1kg = cost of 2kg bag / 2

= £3.80 / 2

= £1.90

Large bag: 1kg cost £1.90

Find the volume and surface area.

Answers

Answer: Formula used for pyramid is (V= 1/3 Bh   SA: 1/2 P*l+B) Final answer is SA=110.4   V=64

Step-by-step explanation:

P= Perimeter

l= length

B= Base

To find the perimeter you add all the sides of the base. (4+4+4+4)=16

To find the length you can use Pythagorean Theorem which is a(squared) + b(squared) = c(squared) where c is the hypotenuse. [tex]2^{2}[/tex] + [tex]12^{2}[/tex]= [tex]x^{2}[/tex]

4+144=[tex]x^{2}[/tex]

164=[tex]x^{2}[/tex]

[tex]\sqrt{164}[/tex]=x

x=12.8

To find the base it will be l*w (4*4)=16

Then you plug it in the formula for SA which will be

SA=1/2 16*12.8+16

SA=110.4

For Volume, it will be

V=1/3 Bh

V= 1/3 16(12)

V= 64
