The first number is 90, the one(second) number is 630, and the third number is 190.
<h3>Word problems leading to the algebraic equation:</h3>
Word problems in mathematics are words written with a mathematical approach and it requires the use of the student's understanding of various mathematical concepts to arrive at a probable solution to the word problems. Word problems are used in mathematics to solve our daily life challenges.
From the given information, given that:
- Let the first number be x
- One(second) number is 7 times the first number. Let that number be
- A third number is 100 more than the first number i.e
The sum of these three numbers is 910. i.e.
x+ y + z = 910
It implies that:
x + 7x + 100 + x 910
9x + 100 = 910
9x = 900 - 100
9x = 810
x = 90
y = 7(90) = 630
z = 100 + 90 = 190

Answer:
1144cm²
Approx. 1100cm²
Step-by-step explanation:
Area of rectangle=
L×B
34×20 = 680cm²
Area of semi-circle=
πr²
3.14 × (10)² = 314cm²
Area of triangle=
½b×h
b = 49 - 34 = 15
<u>2</u><u>0</u><u> </u><u>×</u><u> </u><u>1</u><u>5</u> = 150cm²

Area of shape =
680 + 314 + 150 = 1144cm²
approx. 1100cm²

Answer:
5 times x minus 8 minus 7
Step-by-step explanation:
whenever you see an x right next to a number, it means that it's being multiplied for that number. For example: 2x mean 2 times x
This symbol - is a minus symbol. So when it's in front of a number, you say "minus" and then the number. For example: 4 - 3 means, Four minus three.
Answer:
y-2=-5/7(x+3)
Step-by-step explanation:
y-y1=m(x-x1)
y-2=-5/7(x-(-3))
y-2=-5/7(x+3)
Answer:
A) 0
Step-by-step explanation:
The solution is a couple (x, y) that are the coordinates of the intersection point of the lines.
If the lines are parallel there is no intersection and no solution to the system of equations
