Step-by-step explanation:
Assuming that the total stamp is x
According to the question
Izzati's stamps is 1/4
Ailing's number of stamps is 1/8
X= 1/4 x 1/8 = 5/8 - the remaining stamps.
Rina’s number of stamps is 7/10 x 5/8 = 35/80 x
5/8 x 35/80 = 15/80 - (Susan's stamps)
According to the question
15/80 = 42
X: 224
the total number of stamps originally is 224.
Larry works for a tree farmer and needs to plant new saplings (young trees). He can plant 27 saplings per hour. He needs to plant 178 total saplings and has already planted 16 saplings.
Which equation and answer shows the number of hours (h) it will take for him to plant the rest of the saplings?
Answer:
27h+16=178 I believe would work as an equation for this problem
Step-by-step explanation:
The required time to plant the rest of the saplings is 6 hours, and 27 + 16 = 178 is the required expression.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
Let the number of hours be h,
He can plant 27 saplings per hour.
He needs to plant 178 total saplings and has already planted 16 saplings.
So, according to the quesiton,
27h + 16 = 178,
27h = 162
h = 162/27
h = 6
Thus, the required time to plant the rest of the saplings is 6 hours,

i dont know what to do pls help
Answer:
x = 2.4
Step-by-step explanation:
10x = 24
x = 24 ÷ 10
x = 2.4
Step-by-step explanation:
→ -4 = 20 - 10x
→ -20 - 4 = 10x
→ -24 = 10x
→ x = -24/10
→ x = -2.4
therefore, value of x is -2.4

en un restaurante se usan 70 gramos por cada porción de arroz por persona.Si un día se preparan 4760 gramos de arroz ¿cuántas porciones se obtendrán?
Queremos saber cuantas porciones de arroz se preparan dado que conocemos cuantos gramos de arroz se utilizan.
Se prepararon 68 porciones.
Lo que sabemos en principio es que, por cada porción de arroz, se necesitan 70 gramos de arroz.
Sabemos que en total se utilizan 4,760 gramos de arroz. Para saber cuantas porciones se prepararon, hay que tomar el cociente entre la cantidad total utilizada y lo que se usa para cada porción.
Esto nos da:
4,760g/70g = 68
Es decir, se prepararon 68 porciones.

Four different stores are offering incentives to purchase headphones as shown below.

Answer:
Head Jamz
Step-by-step explanation:
Noisy Music Regular Price $250 Clearance Special - 15% off
If 15% is off then we pay only 100-15 =85% from the original price.
$250 / 100 % = x / 85%
x= 250*85/100 = $ 212.5
Loud N Sharp Regular Price $200 $5 off for every $100 spent
If the price is 200 then will get $5+$5 =$10 discount
Final price will be 200-10 = $ 180
Music Mart Regular Price $300 Mail-in rebate for $115
$300-$115 = $ 185
Head Jamz Regular Price $225 Manager special – 25% off
If 25% is off we only pay 75% of the original price
$225/ 100% = x / 75%
x= 225*75/ 100 = $168.75 is the lowest price

Answer:
7
Step-by-step explanation:
it is a 16 digit credit card number. Therefore, start from the first digit and double alternating digits. Add them and the non doubled digits. should be divisible by 10. For double digits, they are added to make single digit.
9+3+8+3+9+4+7+5+6+1+5+3+4+3+3+x = 73+x

From his home, Dan would have to walk due north to get to his friend Samuel's house and due east to get to his friend Cindy's house. It is 3 kilometers from Dan's house to Cindy's house and a straight-line distance of 5 kilometers from Samuel's house to Cindy's house. How far is Dan's house from Samuel's house?
The distance from Dan's house to Samuel's house is 4 km
The distance from Dan to Samuel house, Dan to Cindy house and Samuel to Cindy house forms a right angled triangle.
Distance from Dan to Samuel house = x, Distance from Dan to Cindy house = 3 km and Distance from Cindy to Samuel house = 5 km
Pythagoras theorem shows the relationship between the lengths of a right angled triangle.
Using Pythagoras theorem:
5² = x² + 3²
25 = x² + 9
x² = 16
x = 4 km
Hence the distance from Dan's house to Samuel's house is 4 km

y=5x+21
Step-by-step explanation:
right now we know y=5x+b, so all we need is b.
graphing it on paper starting at (-4,1), you can go up 5, right 1 because your slope is 5.
you'll get (-4,1) (-3,6) (-2,11) (-1,16) (0,21)

Find the equation that passes through (2, 2) and is parallel to 2y + 4x = 4.5
Answer:
Line passing through (2,2) is parallel to X - 2Y = 4, so, the slope is same as given line.
m = -a/b = -1/-2 = 1/2
The equation is
(Y - Y1) = m(X - X1) => Y - 2 = 1/2(X - 2) =>

I need help with these 2 problems I cant figure out.
I started by labeling the right angle (Angle C) 90º. Next, I wrote down everything in one equation.
2x + 90 + 3x - 20 = 180º (180 degrees in a triangle)
Next, I add 20 on both sides.
2x + 90 + 3x = 200º
I combine like terms (2x and 3x)
5x + 90 = 200º
I subtract 90 from both sides.
5x = 110º
Divide 110 by 5 to get x.
x = 22
======
For problem two, I label all the angles I know.
49º + 80º + r = 180º
I add 80 and 49.
129º + r = 180º
I subtract 180 and 129 and get 51º, which is your angle for R.
For angle X, you know that angle R plus angle X equals half of a circle, which is 180º
We know from before that 129º is 180º without R, so X is 129º
