Answer:
D) 4
Step-by-step explanation:
By remote interior angle property if a triangle, we have:
19x° + (18x - 4)° = 144°
(18x - 4 + 19x)° = 144°
(37x - 4)° = 144°
37x - 4 = 144
37x = 144 + 4
37x = 148
x = 148/37
x = 4
Answer:
Two or more linear equations in the same variables; also called a linear system. ... A linear system with infinitely many solutions. System of Linear Inequalities. Consists of two or more linear inequalities in the same variable.
Answer:
Value of b = =1.25.
Step-by-step explanation:
Direct Variation states that a relationship between two variables in which one is a constant multiple of the other.
*if one variable changes the other changes in proportion to the first.
*If a is directly proportional to b i.e,
then it is of the form
a = kb ;where k is constant variation.
Given: a varies directly as b;
then, by definition of direct variation;
we have;
.....[1]
Substitute the value of a =28 and b =7 to solve for k;
Divide both sides by 7 we have;
Simplify:
k =4
now, find b using same method when a =5;
then;
after substituting the value of a = 5 and k=4 in [1] ;
Divide by 4 to both sides we get;
Therefore, the value of b = =1.25
Answer:
a = 1, b = 5, c = 9
Step-by-step explanation:
3 1/2 ÷ 2 1/4
= 7/2 ÷ 9/4
= 7/2 × 4/9
= (7*4)/(2*9)
= 28/18
= 14/9
= 1 5/9
Therefore
3 1/2 ÷ 2 1/4 = a b/c
Where,
a = 1, b = 5, c = 9
Answer:
45= v
Step-by-step explanation:
9 = v/5
Multiply each side by 5
9*5 = v/5*5
45 =v
