Answer:
a = 2, b = 3
Step-by-step explanation:
The opposite sides of a parallelogram are congruent , so
3a + 11 = a + 15 ( subtract a from both sides )
2a + 11 = 15 ( subtract 11 from both sides )
2a = 4 ( divide both sides by 2 )
a = 2
and
3b + 5 = b + 11 ( subtract b from both sides )
2b + 5 = 11 ( subtract 5 from both sides )
2b = 6 ( divide both sides by 2 )
b = 3
Answer:
4x+60=s
Step-by-step explanation:
x is the constant amount that mus be payed and since it will be payed 4 times you multiply x by 4
and 60 is just added to the quarterly paments that will be payed
annd all of that must equal the price of the item s
Answer:
Step-by-step explanation:
f(x) = 3x + 1 and g(x) = x^2 - 6
(f + g) (x)
(3x + 1) + (x^2 - 6)
3x + 1 + x^2 - 6
3x - 5 - x^2
=> -x^2 + 3x - 5
I hope this helps!
Answer:
use own words
Step-by-step explanation:
An expression is just a mathematical phrase. In this tutorial, you'll learn about two popular types of expressions: numerical and algebraic expressions. A numerical expression contains numbers and operations. An algebraic expression is almost exactly the same except it also contains variables.
in mathematics, an algebraic expression is an expression built up from integer constants, variables, and the algebraic operations (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number)
Answer:
306.6
Step-by-step explanation:
Solution for 14.6 is what percent of 21:
14.6:21*100 =
(14.6*100):21 =
1460:21 = 69.52380952381
Now we have: 14.6 is what percent of 21 = 69.52380952381
Question: 14.6 is what percent of 21?
Percentage solution with steps:
Step 1: We make the assumption that 21 is 100% since it is our output value.
Step 2: We next represent the value we seek with $x$.
Step 3: From step 1, it follows that $100\%=21$.
Step 4: In the same vein, $x\%=14.6$.
Step 5: This gives us a pair of simple equations:
$100\%=21(1)$.
$x\%=14.6(2)$.
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have the correct answer
