Yep! 7x2=14-15= -1 // answer is a
Answer:
X= 12
Step-by-step explanation:
Simplifying
4x + -2 = 46
Reorder the terms:
-2 + 4x = 46
Solving
-2 + 4x = 46
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2' to each side of the equation.
-2 + 2 + 4x = 46 + 2
Combine like terms: -2 + 2 = 0
0 + 4x = 46 + 2
4x = 46 + 2
Combine like terms: 46 + 2 = 48
4x = 48
Divide each side by '4'.
x = 12
Simplifying
x = 12

Answer:
Cos A = (√51)/ 10
Step-by-step explanation:
sin is opposite/hypothenuse
cos is adjacent/hypothenuse
Pythagorus theorem says that c² = a² + b²
10² = 7² + b²
b² = 100 - 49
b = ±√51
It doesn't make sense for a length to be a minus number therefore, we will use +√51.
Cos A = (√51)/ 10

Answer:

Step-by-step explanation:

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
×
+
×
Complete the multiplication and the equation becomes

The two fractions now have like denominators so you can add the numerators.

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 14 and 12 using
GCF(14,12) = 2
14÷2 / 12÷2 =7/6
The fraction
7/6
is the same as
7÷6
Convert to a mixed number using
long division for 7 ÷ 6 = 1R1, so
7/6= 
Therefore:
3/4 − (−5/12) = 
Solution by Formulas
Apply the fractions formula for subtraction, to
3/4 − (−5/12)
and solve
(3×12) − (−5×4) 4×12
=3/6− (−20/48)
=56/48
Reduce by dividing both the numerator and denominator by the Greatest Common Factor GCF( 56,48) = 8
56÷8 / 48÷8 =7/6
Convert to a mixed number using
long division for 7 ÷ 6 = 1R1, so
7/6= 
Therefore:
3/4 − (-5/12) =
