We write to expressions since there are two unknown here which is x and y. The first expression is the <span>sum of two numbers, x and y, is 12.
x + y = 12
The second expression is that the </span><span>difference of x and two times y is 6.
x -2y = 6
Therefore, the values of x and y are 10 and 2.</span>
Answer:
Algebra book weighs 24 oz
Grammar book weighs 15 oz
Step-by-step explanation:
algebra = x and grammar = y
x = 2y-6
5x = 8y
5(2y-6) = 8y
10y - 30 = 8y
2y - 30 = 0
2y = 30
y = 15
x = 2(15)-6
x = 30-6
x = 24
Answer:
<em>There</em><em> </em><em>is</em><em> </em><em>no</em><em> </em><em>atta</em><em>chment</em><em> </em><em>showing</em><em> </em><em>a</em><em> </em><em>diag</em><em>ram</em><em>,</em><em> </em><em>so</em><em> </em><em>the</em><em> </em><em>answer</em><em> </em><em>to</em><em> </em><em>you</em><em>r question</em><em> is</em><em> </em><em>unk</em><em>nown</em><em>.</em>
The exponent of a number says how many times to use the number in a multiplication.
For Example, In 8² , the 2 is the number of times 8 has to be multiplied. In this case It has to multiplied by itself 2 times, 8x8 = 64 so 8² = 64.
Another example is 9³ since the number above is 3 we have to multiply 9 three times, 9x9x9 = 729 which means 9³ = 729.
Hope this helps
