Answer:
Step-by-step explanation:
Because that's the equation given.
To solve for x, isolate the variable and then divide by the coefficient.
Answer:
Given :
Cost of onsite repair = 3 times cost of at store
cost of mai services = cost of at store -10
On-site work completed last week = 15
At store work completed = 40
mail work completed = 5
Let's Assume :
The cost of at store = x
the cost of in-site = 3x
the cost of mail service = x-10
Solution :
Part 1] :
See the "let's Assume" part
The cost of at store = x
the cost of in-site = 3x
the cost of mail service = x-10
Part 2 ]
The equation that can be formed is :
15(3x)+40(x)+5(x-10) = 2650 ,
or, 45x+40x+5x-50 = 2650
or, 90x = 2700
Part 3]
To determine the cost of on-site work, we will solve the equation formed in "Part 2"
So, 90x = 2700
or, 9x = 270
or, x = 270/9
or, x = 30
So,
The cost of on site repair = ₹90
The cost of at store = 30
The cost of by mail service = 20

Answer:
c. 47.7 m
Step-by-step explanation:
If you draw a right triangle to represent the problem, the catheti are the vertical distance from the bird's eyes to the field mouse and the separation from the field mouse to the base of the tree. The 50° of depression is measured from the horizontal in clockwise, the angle that summed with the 50° of the depression can be called α. Then:
α+50=90
α=90-50=40°
The trigonometric function than relates te two catheti with the angle α is:
tan(α)=opposite/adjacent
tan40=40/x
x=40/tan40=40/0.8390=47.7m
Sharee and her two sisters ate 3 /5 of a pizza. How much of the pizza did each girl have? A) 1 /3 B) 1/ 5 C) 2 /15 D) 3 /10
Answer:
B) 1/ 5
Step-by-step explanation:
Number of persons = Sharee and her two sisters = 3 persons
Quantity of pizza eaten = 3/5
Each person ate:
3 persons = 3/5 pizza
1 person = x pizza
Cross Multiply
3 × x = 3/5 × 1
x = 3/5 × 1/3
x = 3/5 ÷ 3
x = 3/5 × 1/3
x = 1/5
Hence, each person ate 1/5 pizza.
Answer:
30inches
Step-by-step explanation:
Circumstances is given by πD(where D is diameter)
Then; from the given
30π=dad
Divide by the both side D =30inches
