Do substitution
2(7-2y) = 5
14 - 4y = 5
-4y = -9, y = 9/4
2x + 9/4 = 5
8x + 9 = 20
8x = 11, x = 11/8
Final answer: x = 11/8, y = 9/4
Answer:
Δ MNO ≅ Δ RST
Step-by-step explanation:
In naming the congruent triangles follow the same order, that is
M is the vertex with 79° and R is the vertex with 79°
MN = 21 and RS = 21
These are the first 2 letter names of the triangles, that is MN and RS
O and T are the third, thus
Δ MNO ≅ Δ RST
Can you show us a picture....
6,702 = 6 thousands and 7 hundreds and 0 tens and 2 ones
= 6 × 1000 + 7 × 100 + 0 × 10 + 2 × 1
= 6000 + 700 + 2.
Above, we have written the number 6,702 in expanded form, or as a SUM of its different parts according to place value.
The digit 6 in the number 6,702 actually has the value 6,000 and the digit 7 actually signifies the value 700. This is why our number system is also called a place value system, because the value of a digit (like 6 or 7 in our example) depends on its placement within the number. In other words, the digit 6 in 6702 does not mean six but six thousand, because the six is placed in the thousands' place. The place of a digit determines its value.
The comma between thousands and hundreds is added as a separator for easier reading. In some countries an empty space is used instead: 6,702 is written as 6 702.
Answer:
After simplifying, the first step in solving an equation with a variable on both sides is to get the variable on one side. This is done by reversing the addition or subtraction of one of the terms with the variable
