Answer:
DCE is 54°
Step-by-step explanation:
To solve this, we must come up with an equation. Since D, C, and E are each straight lines, they are each 180°. then, each line is separating the other which splits the 180 degree line into two parts. For example, E separates D, C separates E, and so on. The exterior angles are given, but the interior aren't. So:
for angle EDC: 180 - (9x - 31)
for angle CED: 180 - (4x + 33)
for angle DCE: 180 - (7x - 2)
we know that all angles in a triangle add up to 180°. So, our equation is:
180 - (9x - 31) + 180 - (4x + 33) + 180 - (7x - 2)=180.
simplify:
180 - 9x + 31 + 180 - 4x - 33 + 180 - 7x + 2=180
540 - 20x = 180
540 - 180 = 20x
360=20x
x= 18
for angle EDC: 180 - (9•18 - 31)=49°
for angle CED: 180 - (4•18 + 33)=75°
for angle DCE: 180 - (7•18 - 2)=54°

How to round 86.415 to the nearest whole number end point
You would round this number by rounding each number (until the whole number) from right to left. So it would change from 86.415>86.42>86.4>87.
Hope this helps, if not, comment below please!!!
Answer:
86
Step-by-step explanation:
I'm not completely sure what this question is asking for. But if you want to round 86.415 to the nearest whole number, it would be 86, since any number less than 5 you would round down, and the 4 in the tenths place is less than 5.

Answer:
y=3/2x+3
Step-by-step explanation:
The slope is 3/2. The slope is m. We plug 3/2 into our equation.
y=mx+b
y=(3/2)x+b
Now we have to find b.
B is 3 because that's where it crosses the y axis.
So y=3/2x+3

A costume designer needs some silver and gold thread for the costumes for a school play. She needs a total of 240 yards. At a store that sells thread by the yard, silver thread costs $0.04 a yard and gold thread costs $0.07 a yard. The designer has $15 to spend on the thread.
How many of each color should she get if she is buying exactly what is needed and spending all of her budget?
Write an equation for the length constraint. Write an equation for the cost constraint. solution
Answer:
Where s represents silver and g represents gold,
Length constraint: s+g=240
Cost constraint: 0.04s+0.07g=15
s= 60
g=180
Step-by-step explanation:
The measurement of silver and gold threads in yards is given as 60 and 180 respectively.
What is a system of linear equations?A system of linear equations is a group of equations having same number of variables and degree.
For the n number of variables n number of equations are required.
On the basis of number of solutions a system of equations can be classified as consistent and inconsistent.
The given problem can be solved as follows,
Suppose the number of yards for silver threads be x and that of gold be y.
Then the equation for the total yard is given as,
x + y = 240 (1)
And, the equation for the cost is,
0.04x + 0.07y = 15 (2)
The value of x from equation (1) is x = 240 - y.
Substitute the value of x in equation (2) to obtain,
0.04(240 - y) + 0.07y = 15
=> 9.6 - 0.04y + 0.07y = 15
=> 0.03y = 15 - 9.6
=> 0.03y = 5.4
=> y = 180
Substitute the value of y in x = 240 - y to obtain,
x = 240 - 180 = 60
Hence, the costume designer should get silver and gold thread of 60 yards and 180 yards respectively.

Round off to the highest place value of 5658
Answer:
6000
Step-by-step explanation:
You want to make the 5 a 6 and zero's for the rest. You make the five a six because if the number is 5 or higher you bump it up one number, if it is 4 or lower you don't need to bump it up or down. I hope this helps!
Place values is the value of a digit in relation to its position
5658 approximated to the highest place value is 6000
The number is given as:
[tex]\mathbf{Number = 5658}[/tex]
The number is in thousands; so, the highest place value is thousands
This means that the number must be approximated to thousands.
When 5658 is approximated to the nearest thousands, the approximated value is:
[tex]\mathbf{Approximated = 6000}[/tex]
Hence, 5658 approximated to the highest place value is 6000

For parallel lines, gradients (slope) must be the same.
The lines given in multiple choice, no line with the same gradient/slope as line y = 3x - 2.
Step-by-step explanation:
From y = 3x - 2,
The slope = 3
Let's check slopes of lines from multiple choice:
From first line
4x + 2y = 5
2y = -4x + 5 (dived 2 both sides)
y = - 2x + 5/2
The slope = -2
Continue with remaining three equations you get slopes: -1/2, -4 and 4.
Hence no equations above represent parallel equation to y = 3x - 2
12x+7<−11 AND5x−8≥40
Answer:
12x+7<−11 x < - 1.5
5x−8≥40 x ≥ 9.6
Step-by-step explanation:
12x+7<−11 First, move the constant to the right. 12x < -11 - 7 Then, we can get the total value and then divide everything by 12. 12x < -18 -> x < - 1.5
5x−8≥40 Move the constant to the right. 5x ≥ 40+8 Then, after we add the constants, we can divide both sides by 5. 5x ≥ 48 -> x ≥ 9.6
