Sav [38]4 years ago

5 0

Answer:

0.5333333333 or 0.53 when simplified.

Step-by-step explanation:

8/15 is simply 8÷15

15 into 8 is not possible so you annex a zero and write a decimal point.The 8 now becomes 80. We now say 80÷15,the answer is 5 because 15x5=75.The remainder is five.We annex another zero and it becomes 50,50÷15=3

I hope this helps.

Find three points that solve the equation, then plot on the graph -5x-3y=-7

kondaur [170]

-5x-3y = -7
5x+3y=7
y=(7-5x):3
1. x=0,=>y=7/3=2 1/3 =>(0;2 1/3)
2.y=0,=>(7-5x)=0,=>x=7/5=1,4 =>(1,4;0)
3.x=1, =>y=2/3,=>(1;2/3)

Find the distance between the points (-3, 9) and (6,-5). Round the answer to the nearest tenth.

inna [77]

Answer:

D. 16.6

Step-by-step explanation:

Here we are given with two coordinates and asked to determine the distance between them.

Here we are going to use the distance formula, which is given as under

$D=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}$

Where

$(x_1,y_1) = (-3,9)$

$(x_2,y_2) = (6,-5)$

Replacing these values in the distance formula

$D =\sqrt{(-3-6)^2+(9-(-5))^2}$

$D =\sqrt{(-9)^2+(9+5)^2}$

$D =\sqrt{(-9)^2+(14)^2}$

$D =\sqrt{81+196}$

$D =\sqrt{277}$

$D= 16.6433$

Hence the Distance is 16.60 units

Paul's Pizzeria sells 45 cheese pizzas and 20 pepperoni pizzas each week.

kaheart [24]

Okay so there are 45 cheese pizzas and 20 pepperoni pizzas
they are asking for the ratio of cheese pizzas to pepperoni pizzas
that would be 45:20
now this needs to be simplified, so divide both numbers by a common factor, which would be 5 in this case...45/5=9 and 20/5=4
so the ratio would be 9:4
