Multiplier method to decrease £262 by 39%

Answer:

It is 68

Step-by-step explanation:

[tex]2x - 10 = x + 6 \\ 2x - x = 6 + 10 \\ x = 16[/tex]

[tex]let \: (y) \: the \: angle \: which \: wanted \\ 90 = y + (2x - 10) \\ 90 = y + (32 - 10) \\ y = 90 - 22 \\ y = 68[/tex]

Answer:

Four hundred seven thousand two hundred nineteen

Step-by-step explanation:

Answer:

If the two polygons are similar, then their sides are proportianal.

We see that sides in the larger polygon are two times as long as the sides of the smaller polygon.

So, if the larger polygon has a side length of 13, then the smaller polygon would have a side length of 13/2, or 6.5

Let me know if this helps!

Step-by-step explanation: multiply both sides by 9m-7 then bring down your 10

that's about all I can remember so your on your own from that point it's been a while since I've did this sorry mate

Answer:

$140

Step-by-step explanation:

250 decrease 20% =

250 × (1 - 20%) = 250 × (1 - 0.2) = 200

200 decrease 30% =

200 × (1 - 30%) = 200 × (1 - 0.3) = 140

Answer:

Step-by-step explanation:

You are given the equation for the number of times, y, that she visits them by distance x. You need only substitute the given x=4 into the equation y(x)

y=-3.5x+20, using x=4

y=-3.5(4)+20

y=-14+20

y=6

So we would expect her to visit her friend four miles away six times a month.

Answer:

70 people visited the waterpark.

Step-by-step explanation:

Since you know that 250 people were surveyed and of those people, 28% of them visited the waterpark, you have to find out what 28% of 250 is. 28% of 250 is 70, so 70 people visited the waterpark.

Answer:

(1/2)x+(1/4)=x

x=0.5

3x+3=2(x+7)

x=11

2(x-5)+7=x+8

x=11

0.8x+5=0.2(40-x)

x=3

5(x-1)-6x=-11x

x=0.5

6(x+2)-x=4(x+4)+7

x=11

(1/2)(x+8)+(3/2)x=10

x=3

Step-by-step explanation:

(1/2)x+(1/4)=x

x-0.5x=0.25

0.5x=0.25

x=0.5

3x+3=2(x+7)

3x+3=2x+14

3x-2x=14-3

x=11

2(x-5)+7=x+8

2x-10+7=x+8

2x-x=8+10-7

x=11

0.8x+5=0.2(40-x)

0.8x+5=8-0.2x

0.8x+0.2x=8-5

x=3

5(x-1)-6x=-11x

5x-5-6x=-11x

11x-x=5

10x=5

x=0.5

6(x+2)-x=4(x+4)+7

6x+12-x=4x+16+7

6x-4x-x=16+7-12

x=11

(1/2)(x+8)+(3/2)x=10

0.5x+4+1.5x=10

2x=6

x=3

Answer:

The length of the sides are 64 cm, 96 cm and 120 cm.

Step-by-step explanation:

Perimeter of a triangle:

The perimeter of a triangle is the sum of it's sides.

A triangle has a perimeter of 280 cm, and its side lengths are a, b and c respectively.

This means that:

[tex]a + b + c = 280[/tex]

a:b= 2:3

This means that:

[tex]\frac{a}{b} = \frac{2}{3}[/tex]

[tex]2b = 3a[/tex]

[tex]b = \frac{3a}{2}[/tex]

b:c=4:5

This means that:

[tex]\frac{b}{c} = \frac{4}{5}[/tex]

[tex]4c = 5b[/tex]

[tex]c = \frac{5b}{4}[/tex]

[tex]c = \frac{5*3*a}{4*2} = \frac{15a}{8}[/tex]

At the original equation:

We replace b and c in function of a. So

[tex]a + b + c = 280[/tex]

[tex]a + \frac{3a}{2} + \frac{15a}{8} = 280[/tex]

Multiplying everything by 8

[tex]8a + 12a + 15a = 280*8[/tex]

[tex]35a = 280*8[/tex]

[tex]a = \frac{280*8}{35}[/tex]

[tex]a = 64[/tex]

Sides b and c:

Since we have a, we can find sides b and c:

[tex]b = \frac{3a}{2} = \frac{3*64}{2} = 3*32 = 96[/tex]

[tex]c = \frac{15a}{8} = \frac{15*64}{8} = 15*8 = 120[/tex]

The length of the sides are 64 cm, 96 cm and 120 cm.
