4x-5=2-x
Answer:x=7/5
Step-by-step explanation:
Answer:
x= [tex]\frac{7}{\\5}[/tex]
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4x−5=2−x
4x+−5=2+−x
4x−5=−x+2
Step 2: Add x to both sides.
4x−5+x=−x+2+x
5x−5=2
Step 3: Add 5 to both sides.
5x−5+5=2+5
5x=7
Step 4: Divide both sides by 5.
[tex]\frac{5x}{5}[/tex] = [tex]\frac{7}{5}[/tex]
In circle O, AC and BE are diameters. The measure of arc DC is 50°. What is the measure of EBC?
Answer:
The angle measure would be 40°
Step-by-step explanation:
Right angles have a measure of 90. Since DC is 50, 90-50 is 40.
The angle measure of ∠EBC would be 40°.
What is arc?The arc is a portion of the circumference of a circle
Right angles have a measure of 90°.
∵∠BOD=90°
Since ∠DC is 50°,
∠EBC = ∠BOD-∠DC
∠EBC = 90°-50° is 40°.
The angle measure of ∠EBC would be 40°.

Amount of Water
Every Week
A
0 mL
B
10 mL
C
100 mL
D
1,000 mL

Three friends are comparing their weekly paychecks. Donald discovers that he earned one-third of Michael's paycheque, and $80 less than Jacob's paycheque. Together, the three friends earned $2920 in one week. How much did each friend earn?
Answer: Michael's paycheque = $ 1704
Donald's paycheque = $ 568
Jacob's paycheque = $ 648
Step-by-step explanation:
Let x = Michael's paycheque
Donald's paycheque = [tex]\dfrac13x[/tex]
Jacob's paycheque = [tex]\dfrac 13 x+80[/tex]
Together, the three friends earned $2920 in one week.
[tex]\Rightarrow\ x+\dfrac13x+\dfrac13 x+80=2920\Rightarrow\ (\dfrac{3+1+1}{3})x=2920-80\\\\\Rightarrow\ \dfrac{5}{3}x=2840\\\\\Rightarrow\ x=2840\times\dfrac{3}{5}\\\\\Rightarrow\ x=1704[/tex]
Michael's paycheque = $ 1704
Donald's paycheque = [tex]\dfrac{1704}{3}=\$ 568[/tex]
Jacob's paycheque = $ 568+80 = $ 648

A line passes through the point (-4,7) and has a slope of 3/2
Write an equation in slope-intercept form for this line.
Answer:
[tex]y=\frac{3}{2}x + 13[/tex]
Step-by-step explanation:
Given that [tex]x_{1}[/tex] = -4 and [tex]y_{1}[/tex] = 7 (from the point given) and m = [tex]\frac{3}{2}[/tex], we will use the equation [tex]y - y_{1} =m(x-x_{1})[/tex]. Therefore, when we substitute the given values to the equation:
y - y1 = m(x - x1)
y - 7 = 3/2(x - (-4))
y - 7 = 3/2(x + 4)
y - 7 = 3/2x + 6
y = 3/2x + 6 + 7
y = 3/2x + 13
y=3/2x+13 is the equation of line in slope-intercept form
What is slope intercept form of line?
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
Given that a line passes through the point (-4,7)
The slope of the line is 3/2.
We need to find the equation in slope-intercept form for this line
Let us find the y intercept of line
7=3/2(-4)+b
7=-6+b
13=b
So slope intercept form is y=3/2x+13
Hence, y=3/2x+13 is the equation of line in slope-intercept form

Hiii, I have a little maths problem. So I have this at the photo. I checked and the answer should be -0,0081 . But I don't get why is it with a minus cuz a rule says: if ,,a" is a negative number and the degree is an even number then we should make the final number positive but here it's negative. I don't get why. I'll give brainliest if you can help me!
Answer:
you are correct with -0.0081
Step-by-step explanation:
but if you are multiplying a negative times a positive it is a negative always. So you do a negative times a negative you get a positive. Then you multiply the positive with a negative to get a negative then you do the negative times a negative to get a negative.

A turkey was cut into 10 equal pieces. If Katie ate 210 of the turkey, and Lorenzo ate 510 of the turkey, how many whole pieces of the turkey are left?
Answer:
3 Whole pieces
Step-by-step explanation:
A turkey was cut into 10 equal pieces.
For Katie
If Katie ate 2/10 of the turkey
Number of Whole pieces of turkey Katie ate =
2/10 × 10 whole pieces = 2 whole pieces
For Lorenzo
Lorenzo ate 5/10 of the turkey
Number of Whole pieces of turkey Lorenzo ate =
5/10 × 10 whole pieces = 5 whole pieces
how many whole pieces of the turkey are left?
This is calculated as:
10 pieces - (2 piece + 5 pieces)
10 pieces - 7 pieces
= 3 pieces
Therefore, we have 3 whole pieces of turkey left.
Answer:
3 Whole pieces
Step-by-step explanation:
A turkey was cut into 10 equal pieces.
For Katie
If Katie ate 2/10 of the turkey
Number of Whole pieces of turkey Katie ate =
2/10 × 10 whole pieces = 2 whole pieces
For Lorenzo
Lorenzo ate 5/10 of the turkey
Number of Whole pieces of turkey Lorenzo ate =
5/10 × 10 whole pieces = 5 whole pieces
how many whole pieces of the turkey are left?
This is calculated as:
10 pieces - (2 piece + 5 pieces)
10 pieces - 7 pieces
= 3 pieces
Therefore, we have 3 whole pieces of turkey left.
Find the value of x
x°
66°
117°
Answer:
x = 51 degrees
Step-by-step explanation:
Keep in mind, the angles of a triangle add up to 180 degrees.
A flat line also equals 180 degrees.
First, we should find the lower left angle. We know that 117 plus that angle is going to be 180, since it's a flat line.
180 - 117 = 63
Now, we just need to find angle x. (All 3 of our angles should add up to 180, knowing this, we can put it in an equation)
63 + 66 + x = 180
Then, you solve for x:
(63+66) + x = 180
129 + x = 180
-129 -129
x = 51
