Step-by-step explanation:
7( 4 - 2x) - 6x = 3
Answer:
x = 1.25
Step-by-step explanation:
7(4 - 2x) - 6x = 3
(28 - 14x) - 6x = 3
-28 - 28
- 14x - 6x = - 25
- 20x = - 25
/ -20 / -20
x = 1.25
A music store marks up the instruments it sells by 30%. If the price on a trumpet says $104. How much did the store pay for it?
Answer:
A. $ 58.50
B. $ 80
C. No, it did not mark up 30%
Step-by-step explanation:
Since,
A. We have,
Mark up percentage = 30%
Actual price = $ 45,
B. We have,
SP = $ 104,
C. We have,
AP = $ 75,
SP = $100,
Thus, mark up percentage =
= 33.33 %
Hence, store did not mark up the price by 30%.
Answer:
$ 72.80
Step-by-step explanation:
30% of 104 = 0.30 * 104
= $ 31.20
Money paid by the store = 104 - 31.20
= $ 72.80

Here is a circle with center H and some line segments and curves joining points on the circle. Identify ONE example of each of the following.
a. Diameter
__________
b. Radius
_________
(Be sure that your book includes your written reasoning.)
Answer:A diameter is a chord that runs through the center point of the circle. It is the longest possible chord of any circle
Step-by-step explanation:The Radius is the distance from the center outwards.
The examples are,
a. Diameter: DG
b. Radius: AH, EH, DH, GH
What is meant by Diameter?Diameter: straight line passing one side to another side through the center of a circle or sphere is known as diameter.the line DG joins 2 points on the circle from one side to another passing through the center of the circle.Therefore, the DG segment is an example of a diameter.Radius: a line segment extending from the center of a circle or sphere to the circumference is known as a radius.The lines HA, HE, HD, and HG, extend from the center of the circle to the points on the circumference of the circle.Therefore, these segments are examples of radius present in the image.
The examples are,
a. Diameter: DG
b. Radius: AH, EH, DH, GH

ano ang fraction ng 0.8
Answer:
this some sortof point tranfer
Step-by-step explanation:
is 8/4 equivalent to 10/5?
These are just some equivalent fractions of 8/4:
2/1 = 4/2 = 6/3 = 8/4
= 10/5 = 12/6 = 14/7 = 16/8
= 18/9 = 20/10 = 22/11 = 24/12
= 26/13 = 28/14 = 30/15 = 32/16
= 34/17 = 36/18 = 38/19 = 40/20
= 42/21 = 44/22 = 46/23 = 48/24
= 50/25 = 52/26 = 54/27 = 56/28
= 58/29 = 60/30 = 62/31 = 64/32
= 66/33 = 68/34 = 70/35 = 72/36
= 74/37 = 76/38 = 78/39 = 80/40
= 82/41 = 84/42 = 86/43 = 88/44
= 90/45 = 92/46 = 94/47 = 96/48
= 98/49 = 100/50 = 102/51 = 104/52
= 106/53 = 108/54 = 110/55 = 112/56
= 114/57 = 116/58 = 118/59 = 120/60
= 122/61 = 124/62 = 126/63 = 128/64
= 130/65 = 132/66 = 134/67 = 136/68
= 138/69 = 140/70 = 142/71 = 144/72
= 146/73 = 148/74 = 150/75 = 152/76
= 154/77 = 156/78 = 158/79 = 160/80
= 162/81 = 164/82 = 166/83 = 168/84
= 170/85 = 172/86 = 174/87 = 176/88
= 178/89 = 180/90 = 182/91 = 184/92
= 186/93 = 188/94 = 190/95 = 192/96
= 194/97 = 196/98 = 198/99 = 200/100
So, yes.

Answer:
542.1
Step-by-step explanation:
Find the number in the tenth place 0 and look one place to the right for the rounding digit 7 . Round up if this number is greater than or equal to 5 and round down if it is less than 5 .
There are 19.3 cups of flour in a bag. The chef uses 2.9 cups for making cookies. Then, he uses 1.2 cups of sugar and 5.1 cups of flour for making banana bread. How many cups of flour are left?
Answer:
10.1
Step-by-step explanation:
19.3-2.9=16.4
16.4-1.2=15.2
15.2-5.1=10.1
so there are 10.1 cups of flower left
Answer:11.3
Step-by-step explanation:
19.3 - 2.9 -5.1= 11.3
You don't subtract the 1.2 cups of sugar because it's only asking about the flour.

Answer this for 15 points
Answer:
A.
Step-by-step explanation:
y = mx + b
y = -2/3 x + b
(x, y) = (3, 0)
0 = -2/3 (3) + b
0 = -2 + b
b = 2
y = -2/3 x + 2
Answer: A.
Answer:
y = - 2/3 + 2
Step-by-step explanation:
Step 1:
y = mx + b Slope Intercept Form
Step 2:
y = - 2/3x + b Input Slope
Step 3:
0 = - 2/3 ( 3 ) + b Input x and y
Step 4:
0 = - 2 + b Multiply
Step 5:
2 = b Add 2 on both sides
Answer:
y = - 2/3 + 2

Using complete sentences, explain which function has the greatest y-intercept.
Answer:
5 9
Step-by-step explanation:
Determine the given equation is a linear equation write yes or no. If yes, write the equation in standard form.
7n - 8m = 4 - 2m.
Use Standard form
Answer:
The equation is linear. Standard form:
7n - 6m - 4 =0
Step-by-step explanation:
Linear Equations
The linear equations are identified because all terms form a polynomial of degree 1 or zero (no variable).
The standard form of a linear equation is:
ax+by+cz+d=0
where x, y, z are the variables, and a,b,c are constants.
The equation:
7n - 8m = 4 - 2m
Is linear, both variables have an exponent of 1 and there is an independent term. Moving all terms to the left side:
7n - 8m - 4 + 2m =0
Simplifying:
7n - 6m - 4 =0
The Leaning Tower of Pisa in Italy was built between 1173 and 1350. A. Write an equation in slope-intercept form for the yellow line. Equation: y= b. The tower is 56 meters tall. How far off center is the top of the tower? The top of the tower is meters off center
Answer:
The answer is below
Step-by-step explanation:
From the image of the leaning tower of Pisa, we can see that it passes through the point (7.75, 0) and (10.75, 42).
a) The equation of a line in slope intercept form is given by y = mx + b, where m is the slope and b is the intercept. Also, the equation of line passing through
[tex](x_1,y_1)\ and\ (x_2,y_2)\ is:\\\\y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)[/tex]
Hence since it passes through (7.75, 0) and (10.75, 42), the equation is:
[tex]y-0=\frac{42-0}{10.75-7.75} (x-7.75)\\\\y=14(x-7.75)\\\\y=14x-108.5[/tex]
b) When the tower is 56 meters tall, i.e. y = 56, we need to find the value of x:
y = 14x - 108.5
56 = 14x - 108.5
56 + 108.5 = 14x
164.5=14x
x = 164.5/14
x = 11.75
When the tower is 56 meters tall, the top of the tower is 11.75 m off center

Help!!! Explain too please
Answer:
5 cm/s
Step-by-step explanation:
The rate of change (ROC) is the speed at which the y variable (hieght) increases with the x variable (time). so ROC = 5.
the linear equation is y = mx + b, m is also the roc, b is the initial value, so,
if y = 60, x = 4 & b = 40, then making m the subject of equation will give the value of the ROC. i.e m = (y - b)/x = (60 - 40)/4.

−z + 26 = 12 what is Z
Answer:
z = 14
Step-by-step explanation:
subtract 26 from both sides to isolate the variable, you should get: -z = -14
then divide both side by the negative sign, so you should get: z = 14
Answer:
z=14
Step-by-step explanation:
−z + 26 = 12
-z=12-26
-z=-14
z=14
