PLS HELP. Write an equation that represents the clues given. Clue #1: The sum of six times the first number and four times the second number is equal to 550. Clue #2: The sum of half the first number and four times the second number is equal to 1000

Clue#1:  6x+4y=550

Clue #2:  1/2x+4y=1000

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

The first number will be x, and the second number y:

The sum of six times the first number and four times the second number is equal to 550

Six times the first number means that the first number must be multiplied by 6.(6x); the same for four times the second number (4x).

6x+4y=550

The sum of half the first number and four times the second number is equal to 1000

Half the first number means the first number (x) divided by 2,or multiplied by 1/2.  

1/2x+4y=1000

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.
